Well, I plan on getting the new iPhone 3G but I don't have a AT&T and have T-mobile; I've been told that it's very easy to unlock it for T-mobile. What programs would I use and if there a tutorial for it? I'm on a mac too. Do I just switch the sim cards too? As you can see I'm pretty darn clueless. There is youtube videos but they don't help. Anything you know about this unlocking thing please pleas tell me I'd like to know anything and everything about it! Thanks!!
