I am still not 100% sure if I will end up getting an iPhone 4 (I'm like 99.99% sure), but a while ago I decided that I would not pre-order it. If/when I buy one (or should I say try to) it will probably be early July. What are the chances of me getting one? I really want it before I go on a trip the first week of August. So if I just walk into an Apple Store on, say, July 2nd, and reserve one, what timeframe can I expect to actually GET one?
