So, how’s your battery life doing under iPhone 3.1? If you jumped on it immediately last Wednesday, or had a few days to try it out at least, have you noticed any big changes? Much better? Much worse? Or is it pretty much the same?

Yeah, we ask this every time there’s a new firmware, but that’s just because Apple seems to be tweaking things every time there’s a new firmware.

So, win, lose, or draw, let us know how it’s working for you. And if you’re having battery problems, remember to check out TiPb’s How To: Troubleshoot iPhone Battery Life Problems guide.

Updating to iPhone 3.1 this weekend? TiPb’s got your back!

• Complete iPhone 3.1 Software Walkthrough

We’re also going to keep track of known iPhone 3.1 issues and bugs, so if enough of us find the same problems, we’ll post on them and they’ll automagically get added to the list.

Go luck and happy updating!

On the fence about downloading iPhone 3.1? Wondering what’s changed since iPhone 3.0? Need a handy link to send your friends who may have questions? TiPb’s got your back with our complete iPhone 3.1 Software Walkthrough.

Previously, we took you through all three beta versions, now we’ll take you through the final release.

And we’ll get started, right after the break.

What Hasn’t Changed

A lot. Too much to list neatly this time around. When you finish reading this walkthrough, go back and read our iPhone 3.0 walkthrough. It’s a giant compared to this.

Still, there are a few talking points…

iTunes 9 Features

It’s also worth noting that a couple of new features touted for iPhone 3.1, like Genius Mixes, and App Management are actually contained in the simultaneously released iTunes 9. See our iTunes 9 Software Walkthrough for more.

Bug Fixes

Big .0 releases are typically followed up swiftly with quick .1 bug fixes. While the swift part here is debatable — though on par with last year’s update — the bug fixes aren’t. Among the issues addressed:

• Better iPhone 3G Wi-Fi performance when Bluetooth is turned on
• Fixes issue that cause some app icons to display incorrectly

Note, we’d heard iPhone 3.1 would also fix the Spotlight issue that displayed deleted emails, but Apple doesn’t list it, and we’ve heard reports it isn’t yet fixed. (Though it apparently was in iPhone 3.1 Beta 3. Strange.)

Home Screen

With the iPhone 3GS and its accessibility features, you can now enable triple-clicking of the Home Button to toggle VoiceOver, Toggle White on Black, and Ask (which then will pop up a menu offering Turn VoiceOver On, Turn Zoom On, Turn White on Black On).

Voice Control

Voice Control in iPhone 3.0, after holding down the Home button for several seconds, let you speak simple commands to place calls and control music. With iPhone 3.1, it will now also work over Bluetooth.

Just hold down the Bluetooth call button as you would the Home Button, let go, and Voice Control pops up. State your command into the BT mic, and Voice Control will “speak” the confirmation (whether it gets it right or not) through the BT earpiece.

MobileMe Find My iPhone Remote Passcode Lock

Expanding on the Find My iPhone remote tracking and wiping service that came with iPhone 3.0, you can now also remotely assign a passcode lock. This is a nice half-way ground between leaving your iPhone wide open, or having to wipe it clean, if you can’t find it but aren’t sure you’ve permanently lost it.

Messages

Still no MMS for AT&T users. That’s being released on September 25 (though whether it will require an iPhone 3.1.1 update, or just a new carrier file is unknown).

For those outside the US with working MMS, you can tap the action button at bottom, left to save them to the camera roll, just like you could previously do with pictures under iPhone 3.0.

Calendar

Calendar gets a minor tweak in iPhone 3.1. Now event alerts also display the location of the event in the popup. Presumably, this is now considered important glance-able information.

Photos

Video trimming is now non-destructive. Previously, if you trimmed a video, it was automatically saved over the original, meaning you could never undo or go back to the full clip. Now, a Save As… dialog gives you the option of preserving the original and creating as many version copies as you want (an short clip to email, a longer one to share to YouTube, and the full clip to sync and bring into iMovie, for example).

Maps

We haven’t seen this show up yet ourselves, but during Steve Jobs’ iPhone 3.1 overview, the slide behind him listed Sponsored Links in Maps as a… feature. (Maybe that’s why Google CEO, Eric Schmidt was there?). Not quite sure how we feel about this in a built-in app either, as opposed to a site we choose to navigate to in Safari…

Settings

Setting usually accounts for the longest list of changes in a new iPhone firmware, but this time it’s fairly short.

Settings: General: Usage now includes a separate meter for Tethering Data. Apologies again, AT&T users, but for those outside the US — if it proves reliable! — it could help avoid nasty overage charges if you exceed your data cap.

Settings: General: Accessibility includes that aforementioned toggle for the Home Button triple-click to enable quick Accessibility switching. Options include Off, Toggle VoiceOver, Toggle White on Black, or Ask which will launch a pop-up and let you choose between the above and Turn Zoom On.

Settings: Safari now, finally, has that toggle to enable Fraud Warnings for malicious web sites (like phishing sites, malware sites, etc.).

iTunes Store

iPhone 3.1 lets you display available iTunes account credit both iTunes Store, and in the App Store, and allows you to redeem gift cards and other promotional codes.

Also, iTunes U is now “better organized”.

In addition, displacing Podcasts (which moves to the other side of the tracks beneath the More tab) is Ringtones, displayed like music, and available ready-made for $1.29.

App Store

Since the App Store is closer akin to a local WebView, it’s fairly easy for Apple to update the App Store (or iTunes Store) without updating the firmware. Case in point, the night before iPhone 3.1 went live, the App Store was updated to feature “Top Grossing” as one of the view options.

Apple has extended their Genius technology to recommend apps as well in iPhone 3.1. The Genius tab appears under Featured, taking the left-most slot. Once you log in, activate, agree to the terms of service (twice!), Genius will crowd-source other iTunes App Store users with similar tastes in an effort to suggest apps you don’t have but might enjoy. (The app on which the recommendation is based is listed on top of the suggested app — nice touch).

As mentioned above, you can now also see your current iTunes Store credits in the App Store, and you can now also redeem iTunes gift cards, promo codes, and certificates here as well. Feature. Parity.

Phone

Copy and Paste comes to the Phone Keypad. Just tap and hold and the input area will change from dark blue to light blue, and the Copy Paste menu will pop up.

The iPhone Paste feature is “smart” enough to change alphanumeric phone numbers to pure numbers (i.e. 1-800-FLOWERS to 1-800-356-9377).

Contacts also get direct copy, so you can hold your finger down on a contact field, just like a picture in Photo, to trigger the copy pop-up menu.

Conclusion

Like the recently released Mac OS X 10.6 Snow Leopard, iPhone 3.1 doesn’t provide a lot of fancy user-facing updates (we likely won’t see those until Mac OS X 10.7 and iPhone 4.0 respectively). What it does is fix things that needed fixing, and fill in missing functionality that needed filling in. And, it throws in a couple small feature enhancements, just because.

Free for both iPhone and iPod touch 3.0 users (iPod touch 2.x users will still need to cough up $9.95 to pay the subscription accounting devil’s dues), if iPhone 3.0 was a must-have for the sheer magnitude of its new functionality, 3.1 is a no-brainer update to make the must-have that much nicer-to-have as well.

[Thanks to everyone who contributed screenshots and descriptions for this walkthrough, especially Justin, Jeremy, and James. If you noticed we missed anything, drop us a note in the comments and we'll update as needed.]

Apple, following their announcement at the It’s only rock and roll, but we like it special music event, has just posted iPhone OS 3.1, promoting it’s Genius App Recommendations, Genius Mixes, Downloadable Ringtones ($1.29 – ouch!), and support for iTunes 9′s App Management feature.

Just plug in your iPhone, hit Update, sit back, and enjoy the new hawt. (Jailbreakers and unlockers should hold off unless you want to lose your jailbreak/unlock.)

AT&T is promising MMS on September 25, along with a software update to enable it. Sounds like iPhone 3.1 to us. Show it off at the September 9 Music Event along with the third generation iPod touch, then release it a couple weeks later to coincide with MMS?

WhenWillApple reports that AT&T MMS is already working for them in Florida under iPhone 3.1 Beta 3. and while it might just be another random network test, could it also be a sign of what’s to come?

Anyone else rocking AT&T MMS on iPhone 3.1 Beta 3? Say where and when in the comments!

WhenWillApple has found another new goodie in the just released iPhone 3.1 Beta 3: Settings > General > Usage now shows Tethering Data alongside the previous Cellular Network Data counter.

Since countries outside the US, and carriers other than AT&T have offered tethering pretty much since the launch of iPhone 3.0, does this new addition, alongside the return of MMS settings in iPhone 3.1 Beta 1 released a month ago, hint that AT&T might finally be getting their iPhone offerings in order?

Insert your AT&T tethering rumor here!

Following up on the recent release of iPhone 3.1 Beta 3, WhenWillApple has posted up a YouTube video (embedded above) showing the new copy/paste functionality for videos.

Like copy/paste for images in iPhone 3.0, this allows you to send copies of your videos without the compression that goes along with the Share function. Just pick a video, tap and hold for “copy”, switch to email, tap and hold for paste.

Again, the size of the email boxes (sender and receiver) will likely still be a limiting factor. (MobileMe allows for 20MB per email, for example).

Apple has released iPhone 3.1 Beta 3 (7C116a) to developers via developer.apple.com, along with notification that iPhone 3.1 Beta 2 expires tomorrow, July 28 at 12am (device local time).

While Apple has previously released most of the betas on Tuesday, a desire to prevent the “pink screen of death” associate with expired betas perhaps necessitated an earlier release this time.

The OS weighs is said to weigh in at around 307MB. Updates to follow below as we get them:

According to WhenWillApple, you can now copy and paste videos into email (like you could images under 3.0) to get full resolution (not compressed like the share option). We’re guessing email box size will still be a restriction…

Also, Tethering Data now gets it’s own counter in Settings > General > Usage.

[Thanks to Davizzle for the tip!]

Apple has just informed developers that a new version of iPhone 3.1 Beta firmware and SDK have been released:

iPhone SDK 3.1 beta 2 and iPhone OS 3.1 beta 2 are now available on the iPhone Dev Center. These versions are for development and testing only and should be installed on devices dedicated to iPhone OS 3.1 beta software development. Please read the iPhone OS beta Pre-Install Advisory and the iPhone SDK 3.1 beta 2 release notes before downloading and installing.

Use the Apple Bug Reporter if you discover compatibility or functionality issues while testing with the iPhone OS 3.1 beta 2 release.

Registered developers can, as stated, grab it via developer.apple.com.

UPDATE: Ars Technica reports iPhone 3.1 Beta 2 allows developers to send apps to test devices via Wi-Fi, rather than having to tether via USB as in previous releases.

According to WhenWithApple, minor changes include new language for the video editing options, now called “Trim Original” and “Save As…” Screenshot after the break!

When/if we come across anything else, we’ll update and add it to our ongoing iPhone 3.1 Beta Walkthrough…

iPhone 3.1 Beta 1 has just been released, and unlike the major new version that was iPhone 3.0, it’s still unclear how many features — compared with bug fixes — will be added. However, enterprising developers have already discovered at least a few things we can all look forward too.

So, here’s TiPb’s iPhone 3.1 Beta Walkthrough, and we’ll keep it updated as/if Apple releases future betas.

Home Screen

The jigglies — what Dieter lovingly calls the little dance icons do when you hold them down long enough to make them moveable and rearrangeable — now make the iPhone vibrate once to further indicate the change of state. Whether or not this will somehow factor in to the iPhone 3GS accessibility features is uncertain.

Voice Control

Voice Control, after holding down the Home button for several seconds, let you speak simple commands to place calls and control music. In iPhone 3.1, it will also work over Bluetooth.

The exact process isn’t clear yet, but it’s hard to imagine anything other than holding down the call button on a Bluetooth headset function similarly to how the Home button currently works.

Messages

After being present in iPhone 3.0 Beta 1 through Beta 4, before being stripped out in Beta 5, AT&T users will again find MMS functionality restored to the interface. However, it’s not functional without hacking the carrier file, and it’s unknown if it will survive until release or be stripped out again if AT&T still isn’t ready for the feature to go live.

Calendar

Calendar gets a minor tweak in iPhone 3.1. Now event alerts also display the location of the event in the popup. Presumably, this is now considered important glance-able information.

Photos

Video trimming is now non-destructive. Previously, if you trimmed a video, it was automatically saved over the original, meaning you could never undo or go back to the full clip. Now, a Save As… dialog gives you the option of preserving the original and creating as many version copies as you want (an short clip to email, a longer one to share to YouTube, and the full clip to sync and bring into iMovie, for example).

Phone

Copy and Paste comes to the Phone Keypad. Just tap and hold and the input area will change from dark blue to light blue, and the Copy Paste menu will pop up.

Reportedly, the iPhone Paste feature is “smart” enough to change alphanumeric phone numbers to pure numbers (i.e. 1-800-FLOWERS to 1-800-356-9377).

When Will it Ship?

If history is any indication, iPhone 2.0 was released on July 11, 2008, and iPhone 2.1 followed some two months and 4 betas later on September 12, 2008 hot on the heels of Apple’s Let’s Rock introduction of the 2nd generation iPod touch. Will we have to wait for another new iPod and music event before we see 3.1?

Our guess is Apple will try to get 3.1 out earlier to fix a few of the more onerous bugs, but as always, only Jobs knows for sure…

Note on Using Beta Software

Unlike iPhone 2.0 Betas, where access seemed much more limited and leaks were few and far between, 3.1 like 3.0 seems to be on every iPhone users want-now list. Also, unlike 2.0 when many devs were seasoned pros, now Apple is touting thousands upon thousands in the program, some seemingly happy enough to enable 3.0 access for the general user base.

However, betas are intended for developers to test and report back on. They’re not as stable, not as snappy, not as feature-complete and anyone trying to use them as a production OS on their main (or worse, only) device is likely to have something less than an ideal experience. People trying to use it as such may wish they could go back to iPhone 3.0 almost as much as they wished for 3.1. Think thrice before taking the plunge.
