There is a guy local to me selling his 16gb, 3g+wifi iPad. His iPad was purchased before the June 7th unlimited plan cut-off date. If he sells his iPad to me can he transfer his 3g service to me or will he have to cancel and I'll have to order new 3g service? If the latter, will I be able to order the unlimited plan or will I only be able to get the limited plan? I'm trying to decide whether I should purchase this 16gb 3g+wifi or just purchase what I really want, a 32gb 3g+wifi. If I can get the unlimited plan I'm thinking it might be worth going with the 16gb iPad. Any advice?
