Don't know if this has been answered, But this is an iOS 4 problem, I've never had this problem in 3.1.2 or 3.1.3. I have an iPod Touch 2G, and everytime I lock my iPod, then unlock and go to my facebook, the wifi disconnects about 30 seconds after unlocking it. I've noticed the WiFi Address is funky. Here's a pic. Please Register or Log in to view images I blocked part of it just in case it was somehow important. Any ideas?
