Apple is pushing the iPhone OS 4 update (iOS) to all iPhone models. The iPhone 4, iPhone 3GS, and iPhone 3G will all run iOS 4. Apple will fix a few things that should have been done long ago, like the ability to organize your mail, organize apps with folders, create your own playlists too – this is not rocket science, it’s a catch up game. Unfortunately not all features will be available to the iPhone 3G; multitasking has been held back due to a slight lack in the hardware department. Expect hacks to come out the day after. All phones will of course get the most important feature of all: iAds.
Now if you’re thinking this multitasking is going to let you basically run any app simultaneously with others, then think again mister 20 tab web surfer. iOS 4 is tight, and it’s going to have to be an accepted use of resources in order for Apple to let it continue kicking about in the background.

Audio services can be maintained in the background, letting other apps keep your audio playing similar to the iPod app. VoIP service will be allowed to continue with register strings info.plist by being set as a UIBackgroundModes key. It’s very possible that other apps will be allowed to run in the back, like voice recorders and such, so keep an eye out on the App store as they will start rushing in anytime soon. Keep in mind that developers have had a bit of lead time to get things going for iOS 4.
