iOS 4 updated: Dropbox, Quota, Fandango, FlightTrack, more

Not only has Apple released iTunes 9.2 to the masses, they seem to be approving and releasing apps updated for iOS 4 compatibility now as well. If you haven't checked your updates tab in a while, it may be time to tap that App Store icon on your iPhone or check in iTunes.

Out of my 100 or so apps I have installed on my 3GS, I've seen about 4 or so apps in the past 12 hours receive updates for iOS 4 compatibility. I'm assuming that number will only grow over the next couple of days as developers ready themselves for the release of iOS 4. Now that doesn't mean they have any iOS 4 specific features -- it just means they've been compiled with the iOS 4 SDK.

Some apps will have much more significant updates than others of course. So far I've seen updates for apps such as DropBox, Quota, Fandango, FlightTrack and a few others. Quota is touting the fact that it's supporting the higher resolution of the iPhone 4 in its update straight away. I'm curious to see which other developers will do this straight out of the gate. I hope most do as I can't wait to run higher resolution applications on my new iPhone 4!

Streaming music, navigation/location, or VoIP (voice over IP) app in the background are some of the big ones of course. Saving state for fast task switching is something we hope is also rolled out quickly and universally.

Hit the break for some screenshots of some I've found as well as a video from one of our readers demonstrating the in-app SMS feature Apple has given developers and API for. Thanks Ethan! Any of you find any apps that are running iSO 4 compatibility yet? Leave 'em in the comments!!

Help and how to editor for iMore. I can take apart an iPhone in less than 6 minutes. I also like coffee and Harry Potter more than anyone really should.

I would like to note that all the devs have to do to enable system state saving is to recompile using the new SDK. However, the finish tasks in background threads feature does require some coding.

So basically it's a easy way to quickly send text in an app to a contact, or you could delete it and send a random text to any contact.

You can tell which apps are 4.0-compatible when they have a little "+" on them, like iTunes+ music.
Pretty smart of apple. Just checked out a few and wow, saved-states are just as amazing in third-party apps.

@Adam
Actually, the plus means that they will work on the iPhone and the iPad, not that they're iOS 4 compatible.

@Ben
Yeah, pretty much, sadly enough. It pretty much saves you two steps:
1. It auto-copies and pastes your message into the text entry field (and possibly the contact for auto SMS people, but none of those apps that I have that do that have been updated yet).
2. It returns you back to the app after you've hit the "send" button.

I'll take it honestly. It does save me two steps, and I like that. I hope devs put this into apps, who wouldn't want this.

Call me a skeptic, but programs that have never tracked their state are not going to suddenly become stateful and serialize it out just by flipping a compiler switch. It just does not work that way, or if it does, it would only work for grossly defined categories (which Contoller I was using, etc.)

The Newton's Cradle: Physics++ app for iPhone/iPod/iPad has been updated to support multitasking for iOS4. I have tried it and it really works well.

Do a search on it, or pay the Apple developer fee and go to the forums and also read the release notes on the SDK and multitasking.
If you recompile against the newest SDK, it will indeed put in the state saving, but that's the only (and most basic) multitasking option that is enabled. If you want the other ones (task completion, streaming audio, etc.), you must code that in.

My take on this particular matter is straightforward. If it weren’t for my doggy I might have no purpose to live. We’ve been with each other every day since she was 2 or 3 weeks old (she’s nearly 5) and I couldn’t imagine leaving her; or for that matter being without her.
