Hello, I recently purchased a jailbroken and unlocked iPhone 2G, running version 2.2. It does not have a SIM card. I've noticed that it is usually unable to find a WiFi connection, even at home (we have WEP encryption, and it has found it a few times). At the college, there is no encryption and it has never found the network. My 2G iPod Touch and my computers are able to find these networks in the same places with no problem. Is there any way I can fix this?
