Hello all, I have a Iphone 4 with sim card (gsm) and I need to unlock it to use with a different carrier. Will jailbreaking it also unlock it? I have done some searching and all the information I have found has been regarding the Iphone 4's without the sim card (cdma), so this is why I am asking this question. Also, the Iphone has version 7.0.2, what program would be the best at jailbreaking it if it also unlocks the carrier. Thank you guys for your time.
