Mine is having problems pulling data over wifi at times. Like right now. I have a N and G network setup, the G was just for my iphone 3G and what the 4 is connect to. Most of the time it works fine. Now safari is saying it cannot open page server stopped responding. Any data apps won't connect either. However I'm posting this on the same network. Even switched to the G band to make sure. Sometimes it works fine. Others nothing will load. A reboot didn't help. anyone else having similar problems Edit: Ok so somehow the phone thought its IP address was in base 10. a lease renew set it back right to 192. Weird.
