After 7 years of the Blackberry life on T-Mobile, its finally time to make the move! I want to preorder the iPhone like everyone else tomorrow night, but can I do it since I don't currently have an account with any of their carriers? Are you allowed to sign up from scratch during the pre-order? I thought about transferring my number and account tomorrow, but am fearful that they won't let me upgrade to the iPhone 5 a day later.. Due to this dilemma, Im thinking my best bet is to show up at a store on Sep 21st, but I would have to sneak away from work to do so.. Do you guys know how many units per store, or how long iPhones remain in stock on release day? Also the date posted everywhere is Friday Sep 21st, do they always deliver on the day that they promote? Or is that the day they ship them out to you? Im leaving on a trip on Monday Sep 24 and wouldn't want to risk not having a phone on it.
