Last time we posted about a iPhone 4 Unlock Video published on the web from a guy who claims to have unlocked a factory locked Apple iPhone 4 using test sim card . Here is some pictures uploaded by a Chinese guy who claims to have unlocked iPhone 4 using IMSI unlock technique using blank micro sim and other accessories listed below.
He is using software to hack and overwrite the IMSI values on another sim card which is then used to unlock the factory locked iPhone . It is in a way creating your own custom made Gevey Sim as it uses the same technique in use on Gevey Sim Interposer or Rebel Sim . The guy used China Unicom Sim card for the above hack according to the translated version of his tutorial posted online .
