I have an iPhone 4 running iOS 6.0.1 with baseband 03.10.1 and I am looking for a way to unlock it so I can use my own SIM card. What are the available options for unlocking this specific device configuration?

Unlocking an iPhone 4 with baseband 03.10.1 cannot be done via software tools like UltraSn0w, which only supports the 01.59.00 baseband. To unlock this device, you must use an IMEI factory unlock. The best approach is to contact the carrier the phone is locked to and request an official unlock. If you are not the original owner or do not meet their requirements, you may need to use a third-party IMEI unlock service. Note that hardware-based unlocks like Gevey SIM are generally unreliable on iOS 6.0.1.
