Hi,
I just got my iPhone, unlocked, version 1.1.3 from my boss. However, there seem to be some problems connecting via wifi: I can't seem to connect to my network. My friend has an iPod Touch which works fine. I can't connect to my home network or my university network, both work for his device. These networks are both unprotected. The networks are found but when I tick the blue arrow button, the IP/subnet/dns fields are all empty. Filling them in staticly doesn't make Safari work either, but there is a IP (probably forced though). I've tried several things, such as hard reboot, soft reboot, reset network settings, forget this network and many combinations of this.

Anyone know what may resolve this? Thanks a lot in advance.
