3g iphone 16 gig with 7.4 gigs availible version 2.2.1 (5h11) carrier at&t3.1 So I have a wifi home network that works for everything but itunes and the app store apps on my iPhone, the message I get is "cannot connect to itunes store" on both the app store app and itunes. However I have recently discovered if I turn off my wifi on the phone I can use both apps on 3G. Everything else works over wifi on my phone, I have not had any problems with safari or any other apps, they all work fine. I would love for itunes and the app store to work though. I have turned my phone off and on numerous times, reset it by holding the home key and on/off switch numerous times and have unplugged my wifi a couple times to try and reset it. My home wifi is a linksys with a password. I would really apreciate any help!! Is it a settings deal under wifi settings in the phone? Should I have it forget this network and re-do that long password in the wifi set up? Sorry for being a computer tard. Thank you so much in advance.
