I pre-ordered mine to ship because when I did a pre-reservation to pick up the iphone 3GS at an Apple Store, they told me that it is based on first come first serve basis, meaning that they dont actually hold your item at the store, it is dependent on how many of this items come into that particular store. Basically if you are not in line with your reservation printout in hand battling the other reservation people, no matter if you get there before 3pm or not, your item could be given to someone else...not sure this is true or not...but I wasnt taking the chance with this type of release. I have heard plenty of horror stories of Apple stores screwing up reservations...right now my Ipad is sitting safely on the ground in Lousiville, KY awaiting Saturday delivery. I wish everyone luck with your stores. I hope what I dealt with is not true.
I'll be getting there at 7am no matter what. I'm pretty sure I'll get one
