CutYourSIM was one of those rare software-based unlocks for Apple iPhone 4 that managed to unlock the device at higher basebands. Even the iPhone Dev Team has been unable to get this job done, but apparently CutYourSIM sneaked through some white-listed IMEI numbers from Apple’s database, and started offering unlocks for iPhone 4 at higher basebands, while Ultrasn0w 1.2.1 software could crack just the baseband 01.59.00.
Well, if someone really gets through white-list IMEIs, do you expect Apple to keep quiet? Most certainly not; they’ve figured out how CutYourSIM was unlocking the devices, and isolated those IMEIs from their database.
The result is pretty obvious; CutYourSim gave this official confirmation that they won’t be able to offer the service anymore -
“Unfortunately, we were not able to complete the rest of the unlocks waiting in our queue due to our suppliers being unable to offer the service anymore; there is a possibility that the service may return, but we don’t know when, so we have decided to start processing refunds for any orders that we were not able to complete.”
So, once again Apple has been able to defend the iPhone 4 unlock at higher basebands, and same is the case with iPad2. It’d be interesting to see how long Apple succeeds to trick the iPhone Dev Team and prevent them from unlocking the iDevices at higher basebands!
Remember, you can still unlock your iPhone 4 at higher basebands with Gevey and Rebel Sim Cards.
