Doubt it, but the worse answer you'll get is no. Honestly, if you haven't bought one yet you might as well wait the 2 days since you're going to have to wait for an iPhone 5 either way...the likelihood finding one in a store is pretty slim right now and ordering has a waiting time of 3-4 weeks right now. So in the current scenario, 2 days shouldn't mean much unless you know for sure you can get your hands on one now.
Yeah. so, i have a different question. I just checked my upgrade eligibility through the apple website and it is letting me buy an iphone 5 for $300... but the Verizon website won't. Why?
