SIM interposer not working


Standard Member
I recently bought a Gevey Ulta S to try to unlock my iphone 4s but it is not working.
I have tried the plug n play method, I have tried selecting Fido Canada.
I have also tried putting in 3 different codes for Fido and Rogers.
Each time, the phone looks like it registers on the local network "Three" in the UK. However, the phone then restarts itself and bings up a "you need to activate" screen.

What iOS are you running? If you are running iOS 5.1 - 6.0.1 it should work. If you are running iOS 6.1 or above, it won't work.
