Well I just got my iPhone 3gs yestersday and was going to try it out for the 30 days and then make a decision. Well, I only needed one day to be convienced and I'm converting over to AT&T from verizon's blackberry storm. Can anyone advise on proper procedures to sell a blackberry? I mean do I need to unreister from the pin? Remove verizon's sim? Change any email settings?.......etc. Any help is appreciated. I would like to make sure a smooth transaction for both parties
