Like the title says, I'm a current T-Mobile customer but really want an iPhone. I would like to go to AT&T since I like GSM better than CDMA but I'm choosing Verizon for certain reasons. I have some questions though: 1) How do I port my number from T-Mobile to Verizon? Will this be a hard process? I'm going to keep my line active on T-Mobile btw so I would essentially port my number to VZW and change my current T-Mobile number. 2) If I pre-order from Verizon will I get it a day early? Will I have to pick it up in store? Thanks!
