I know it was bought recently (last two months). I am unsure what model it is. It is on at&t and it does have the trackball instead of track pad. Any idea how much it would be worth or how much the exact model is going to affect the price? a ballpark range would be nice.. While it is not mine.. I may try and talk my parents into selling it and letting me get an aria for it. If they decide to keep the money then that is fine but, i at least want a ballpark range on how much they may be able to get for it.. My stepdad bought it.. then after 30 days really decided he didn't like it, and paid full price for iphone 4... sooo.. yeah. They were against me getting any sort of data plan earlier but, I'm kind of hoping now that they both have one.. maybe they will be more open to me get one.
