What is GEVEY Ultra S and how it is different to Ultrasn0w Unlock
GEVEY Ultra S SIM is a passthrough SIM card that allows you to unlock the SIM on their devices without having to jailbreak the iDevice. It is a SIM-sized piece of plastic, which users insert into their iPhone along with a SIM card to free it from carrier restriction. As compared to the iPhone Dev-Team’s ultrasn0w unlock, Gevey Ultra S is hardware based paid unlocking hack, but tethered.
With GEVEY Ultra S, there is no need to jailbreak your iPhone 4S device or change the normal SIM card. No need to cut the SIM card. Just insert the SIM card and insert the Gevey Ultra S in your iPhone (As shown in video demo). It is worth noting that this piggyback doohickey doesn’t require dialing 112 either. It is also compatible with all GSM iPhone 4S SIM Cards.
It unlocks ALL worldwide networks (including USA AT&T). The best part of this hardware unlock is that it doesn’t void your warranty since it doesn’t require any sort of hardware alteration or modification.
