Gevey recently announced the Gevey Ultra S SIM interposer which unlocks your iPhone 4S without the need for dialing 112 or jailbreaking. The makers claim to be using a new exploit that 'fully unlocks' your device.
We've had to opportunity to test the device and can confirm that it successfully unlocks the iPhone 4S on 5.0 and 5.0.1. The Ultra S does not yet support 5.1 so those who have updated (against all warnings) are out of luck for the time being. However, the team says they are "currently working diligently to unlock 5.1".
Take a look at the video below for instructions on how to use the Ultra S. It can be purchased from the link below for $59.99.
