I'm planning on buying an iPhone 5 this Friday (well, hopefully), as I couldn't preorder through the Apple Store Friday morning due to my AT&T line being under my dad's business account. Because of the inability to pre-order on Apple's website, I've become worried that I may not be able to buy it in person on Friday using my upgrade (my last iPhone was a 3GS, and my contract ended last year, so I am ready to upgrade to a new phone). When I bought my 3GS, it was at the Apple store and I didn't encounter any major problems, nor did I when I purchased the original iPhone back in 2007. Is my unease validated, or should I be able to purchase in person with no hassle?
