help i have quickpwn a 2g iphone and added apps from cydia most from bigboss and after a few minutes my screen goes to the home screen with only 0 -3 icons on a black screen with a grey bar like the new 3g iphones. i cant do anything except turn on and off the device. i tried going to back ups on itunes but they dont work, and the only way to fix this is restoring firmware on itunes, then win pwning then quickpwning but this is the second time that this has happened to me and i dont know how to stop this.

Im asuming its a 3g app in cydia (not displayed as 3g) and wrecks havoc on 2g when downloaded. please can someone tell me what app is doing this (as to avoid) and / or a simpler way of fixing the problem (as my solution takes 4 hours)
