I just bought an iPhone 4 at the at&t store last night and have been playing with it since. Unfortunately buying apps (new or updated) from the phone does not appear to be working. When I select a new or updated app and enter my password (which I know is correct, it is not complaining about that) it starts to download the first app and stays on "Loading..." forever. I can connect it to iTunes, delete the app, and then reinstall the app from iTunes and it works fine. Are others seeing this issue? I am running iOS 4.1 (it came that way). On another note I cannot find the iPhone 4 Case Program by searching the App Store on the phone, but I do fine it in iTunes. I guess I will have to wait until tonight and download it at home. The reception (at least in number of bars) is nowhere nearly as good as the LG VU that I replaced. I constantly got 5 bars with the LG at home, but the iPhone varies from 1-4 bars (I have never seen 5 I don't think).
