Hi, I have an iPhone 3GS, and I have successfully unlocked it using Ultrasnow.
The thing is, everytime I turn on 3G, the phone just loses its signal completely. Is it because the unlock does not support 3G or have I done something wrong? If so, how do I remedy it?
Also, ever since the unlock, the "cellular data network" bit is gone, thus, can no longer change the APN, username and password for use on a different carrier.
