i have T-Mobile and i want an iphone because of its’ features. i’ve seen unlocked iphones and i know what they are, but is it really worth the buy? i’ve heard a rumor that aplle created a software thing that relocks your iphone if you try to use itunes or update any software. i want to know what are the pros&cons of getting an unlocked iphone. How will i upload music? can i still download certain apps? does it still function like a locked/original iphone? i really want the iphone and keep my plan with T-Mobile, & can’t afford&wait for the mytouch for T-Mobile, but i really don’t run the risk of it locking back up on me. so if anyone can help me, i would really appreciate it. THANK YOU
