I just recently got a 3rd gen 32GB iPod Touch and updated it to iOS 4 right away. You can see a lot of great updates right on the spot and since I have no life and have nothing better to do, I’ll go through those updates. I’m sure a lot of people have already seen them and are enjoying it :D
This is what is would look like generally, but this is the iPhone
1. The most noticeable thing – the wallpaper. I HAVE BEEN WAITING FOR THIS! Being able to customize your home screen wallpaper :DDD of course, it’d be better if you were able to move the icons wherever you want, but that’s just asking for too much. After all this IS Apple we’re talking about. But yeah, you can set different images for your lock screen and home screen wallpaper.
2. Multitasking is now here. You just press the home button twice (really fast though….seriously xD) and then a row of recently used apps show up on the bottom. Keep scrolling to the right to see all the apps you’e used (I honestly don’t know exactly how many apps this keeps in the list….perhaps all O.O) and if you scroll all the way to the left, there are your playback controls. You can long press on the icons as you would on the home screen (when moving icons). Doing this allows you to delete apps from the list so that you’re not wasting battery life or ….whatever xD apparently, this multitasking is supposed to SAVE battery life, but I wouldn’t count on that.
