There is a guy advertising on craigslist that he can unlock the iPhone 4.2.1. I bought my wife a iPhone 4 yesterday and even though the firmware is 4.1, the modem is 2.10.04. I emailed him about it and he said he can unlock it. Is ere any truth to this because when I checked online, it says that 2.10.04 cannot be unlocked yet. If he is lying, I'm guessing he just wants to meet up so he can steal the phone or something.
