So last year I had my 3gs stolen so I went to a blackberry 8900 which made me switch data plans but now my 8900 is broken.. so right now my date says 6/20/2010.. but will i still be able to pre-order tomorrow for discounted price? and if not then if i put my sim card in my dads 3gs and call att to tell them to switch to iPhone data plan, then will my upgrade change?
