Well, my friends iphone was on 3.1.2, and was unlocked. However, he had used blackrain to unlock, and he had wifi issues. I said id look into and try and help him by updating it to 4.0, and unlocking it. Now, atm, i have cydia on the iPhone, but cant seem to find any wifi networks. Both my networks arent hidden or anything, why cant i find any networks on it?
