i need a new phone and i have considered the possibility of getting an iPhone and then unlocking so it will work with T-Mobile. 1. what is 3G? 2. i have been researching the iPhone with T-Mobile and ive seen some articles that say the 3G iPhone is going to be available for T-Mobile as well. is this true? if so then... 1. when will it come out? if not then... 3. how easy is it to set up your iPhone to work with a different provider other than AT&T? ie T-Mobile? Thanks so much. I eagerly await your replies.
