I returned my iphone with much difficulty today see post #20 at this thread -> http://forums.macrumors.com/showthread.php?t=967504 Because I couldn't use it where I live/work -> http://forums.macrumors.com/showthread.php?t=966574 And started using my IPhone 3G. Here are my withdrawal symptoms The good - No nagging feeling about a faulty iphone in the pocket - No fear of picking up calls from work, when you know its going to drop, the moment you pick the phone up! - The 3G feels much more comfortable to hold in my palm, due to its curved back. - I don't miss the multi-tasking. The bad - things that I miss about the iphone 4. 1. Battery life. My 3G sucks at battery life. 2. Speed. Clearly iphone 4 was snappy and responsive. With the 3G I feel takes 2 or 3 seconds more than the iphone 4 in launching apps. 3. Camera/video. 3G has no video, and the photos that it takes are not as good as the ones that the iphone 4 took. I think I will miss the camera/video when opportunities to use them arise. If you've returned your IPhone 4 and have moved back to using your 3GS or 3G please post your experience/withdrawal symptoms if any.
