There's a new iPhone 4S unlocking method, which achieves a full unlock using only an Ultra S SIM card. Gevey Ultra S SIM is claiming to unlock your iPhone 4S on baseband like 1.0.11, 1.013, 1.0.14, for which the whole world is waiting anxiously. It is actually a thin card that squeezes in alongside your usual SIM card to run the exploit. It spoofs your AT&T IMSI number and authentication key (Ki) supplied by the SIM card to the network for misguiding the iPhone, then your card IMSI is used for network connection. It can then be used on any mobile network (like T-Mobile) with which they are technically compatible. More Stable, Minor bug Fixes, Compatible with more SIM's.
