I am wondering if anyone else is having similar problems with 3g (probably with edge too). If I use wifi, everything magically works again. However, if I switch to 3G...the app store stops working and so do all the apps that require a connection stop working. The thing is, the 3G isn't working most of the time but sometimes it does. I've done both types of reset and the only thing left to do is a restore. Still trying to see if this problem is just me.
