Until DevTeam posts an update about the unlock progress on twitter, people can try out the Gevey Unlock method which has been reported to unlock iPhone 4 BB – 3.10/4.10, that is, all firmware starting from iOS 4.0 to iOS 4.3. The method works on a sim interposer which forcibly activate the baseband using the emergency dialer.
The detailed process is as follows :
The sim interposer works by adding a EEPROM chip to your sim card just like a Turbosim. Then a number – ’112′ is called from any GSM phone which is free of charge and independent of any carrier. Once the call is connected, you need to hang up the call and turn off/on the airport mode. When the network connection is resumed, you will be unlocked.
The method is not suggested as the given number cannot be dialed in many countries. Also, the unlock is messy and you loose the signals frequently.
