Hey guys, been lurking around lately but my iPhone 4 which was 4.1 jailbroken and unlocked got water damaged so I had to get a new one. YES, apple even gave me a free one because the guy claimed that something was wrong with it even though the phone didnt work? Yeah, he did his little tricks with the flashlight but hey im not complaining. Now, I'm totally lost on whats new out here and was wondering is it even possible to unlock the recent firmwares anymore? I was given a new iPhone 4 with the following details ; Version: 4.2.1 Firmware: 3.10.1 From reading a bit, I know we can jailbreak it but can we unlock it? Or should I just go ahead and upgrade to the 4.3.
