I've read that on launch day Carriers prioritize 2-yr contract customers and won't sell you just a contract free iPhone. I take it the Apple store is different than this though?
I've bought iphones before on release day, but it's possible this year is different. I also didn't buy my ip5 on release date, so am not sure what they did last year with this. Carriers on the other hand will do anything to avoid selling a full price phone, even months after release, but you can just order it on their website.
