We let you know a couple days ago there were a few apps that had already been updated via the App Store to support iOS4. Since then we’ve seen a few more roll out.  Some developers have really taken advantage of the new APIs in iOS4.  Others seem to just be adding compatibility at this point.  Let’s hope a lot of them are working on substantial updates.  Hit the jump for some more iOS4 compatible apps!

Evernote

Evernote (version 3.3.5) is one of the first I’ve seen to implement quite a few 4.0 APIs.  Not only does it come complete with fast app switching integration, but your notes will also be able to sync in the background.  This will be extremely useful for users who like to upload pictures.  I’m always doing this when I’m comparing prices.  I’ll take pictures of SKUs from different stores and tag them accordingly which allows me to flip through later and compare which ones are cheaper and which ones have rebates attached, etc.  Much easier than writing a note with all that information.  The down side to that has always been pictures take a bit to sync with the Evernote servers at times and keeping the app open the entire time was somewhat of a pain. Thanks Evernote! (Read more about Evernote and iOS4 here.) [iTunes link]

LinkedIn

For now, it looks like LinkedIn has added support for fast app switching, but I don’t see much more than that at this point.  I’d love to see the LinkedIn app get a lot more intuitive than it is.  Hopefully they’ll be adding more support in future updates.  If you caught anything I didn’t on this one, let us know in the comments!

Windows Messenger

Not only is this one new to the App Store, it came out of the gate with iOS4 integration built-in.  It also supports alerts for Hotmail as well, so you’ll get notifications in-app when you receive new e-mails via your Hotmail account.  And again, if you see anything worth noting, let us know!

Pandora

I know a lot of you have been waiting for this one. This update just hit the app store a few short hours ago. Pandora background streaming was demonstrated at WWDC 2010 and lots of users were excited to be able to allow Pandora to finally run in the background. This feature has been available for other mobile platforms for quite a while. [iTunes link]

Loopt

Loopt is another company that’s taken advantage of additional APIs available behind iOS4. Fast app switching, PNS alerts, and grid based navigation are a few of the features the new version of Loopt offers. [iTunes link]

WordPress

One of the most popular blogging engines on the planet comes out on release iOS release day claiming Retina Display support? Even if they’re just scaling text and UI elements, good on them. [iTunes link]

Know of any other iOS 4 compatible, feature-empowered apps that we may have missed? Drop them in comments and we’ll include them in the next round up.

Loopt has not only launched a new iPad app this week, Loopt Pulse [Free - iTunes link], but now a new version of their iPhone app as well [Free - iTunes link].

What’s the big difference? How about the ability to easily find interesting people, places, and events with just your iPhone and Loopt’s map screen. Yawing in the middle of a droning conversation, eyes drooping at a lame party, not sure where to go in the center of sleepy-town USA? Loopt’s full-scale assault one boredom just might have your back.

There’s also a new version for BlackBerry, if you find that interesting.

My Canadianess prevents me from trying it (location services are typically highly region-sensitive by virtue of their content partnerships), so if you give it a whirl let me know if I’m missing out.

Tapped on App Store and what did I see? Updates for Tweetie, Loopt, Foursquare, and Flickr — and a couple of those say iPhone OS 3.2 (aka iPad) right there in the What’s New listing. (Yeah, that doesn’t mean 3.2 is coming to the iPhone or these are 1024×768 versions, likely just that they’re built using that SDK for maximum blackboxing on the iPad).

Tweetie [$2.99 - iTunes link] has just hit version 2.1.1 and brings iPhone OS 3.2 compatibility(!), Foursquare (4sq.com) integration, Vodpod video uploads, Post ‘message’ parameter to TwitPic, and Instapaper Mobilizer. See our previous Tweetie coverage for more on the app.

Loopt [Free - iTunes link] expands the product’s Pulse feature to include tens of thousands of local events, and allows check-in to events, public Tips, and the ability to RSVP to events posted on Facebook. It’s also got you covered for SXSW, and adds content from SonicLiving, Zvents and Metromix.

Foursquare [Free - iTunes link] brings a whole new look and feel (see below), faster, better checkin, and categories for Places view. Also, it has history for Places, and uses Tweetie-style pull-to-refresh.

Flickr [Free - iTunes link] iPhone OS 3.2 support (!)

Loopt [Free - iTunes link] has added curated restaurant and bar recommendations via a partnership with TastingTable. With more and more location-based apps and services becoming available on the iPhone, we’re once again seeing a lot of crowd-sourcing (where users enter locations, ratings, tips, and recommendations) used to power it. Loopt, one of the original location apps, is going the other direction and using TastingTable’s team of editors to provide an expert level of detail for potential customers.

Crowds can typically cover more, curators can typically cover better. If you try out the latest version of Loopt, let us know how the new recommendations work for you!

Loopt [Free - iTunes link], which matches social networks with location-based services into one smoldering hot Web 2.0 sammich, has struck a deal with AT&T that will let them update their iPhone users’ location information even when the Loopt app proper isn’t running.

Yes, you read that correctly — the Loopt iPhone app isn’t being granted any extra special background multi-tasking sanction by Apple for the iPhone, this is strictly a server-to-server, Loopt-to-AT&T deal, and it will come at a price. BusinessInsider scores the scoop:

Loopt will first offer the new always-on service in a trial for 5,000 users. You can sign up at Loopt’s site using your iPhone’s MobileSafari browser. After the 14-day trial, the always-on feature will cost $3.99 per month, added to your AT&T bill.

BusinessInsider also renews that old rumor about how Apple is seriously considering limited multi-tasking in a future software update. And, yes, they’ll have to have something interesting to tempt users with in iPhone 4.0/4G next summer, so why not run with that? We’d like it!

But back to Loopt, anyone dying to give AT&T an extra $4 a month for precise stalking tracking of their friends and family?

I watched the recent Apple iPhone commercial, the one featuring Loopt that promised to keep me in stronger, better, faster contact with all my similarly teched-out friends, and immediately fired my iPhone to download it.

But guess what? It didn’t show up in the App Store. Dieter was kind enough to send me a direct link, so I clicked on that, and know what happened? I got a pop-up telling me Loopt wasn’t available in the Canadian App Store.

So, either we Canucks have no friends to stay in contact with, Loopt has yet to expand their offering to our frozen shores, or Apple didn’t bother to make a commercial with wider appeal than AT&T’s network coverage (or all of the above?)

In a global village, is it odd that an App isn’t just an App, and often medieval licensing rights prevent real parity in services?

For our international readers, any other Apps you’ve been unable to get due simply to where you live? Any Americans ever come across an App you couldn’t get?

iPhone ads show cool things being done easily. Case in point, the latest spot featuring Loopt.

Stay in touch with your friends. That’s the iPhone. Done.

Maybe that’s why the iPhone ranks #1 in satisfaction?
