I've seen only talk about pre-ordering the iPhone through Apple and the phone carriers...is there any downside to going through Best Buy or Radio Shack? I stopped by Radio Shack on my lunch break and was told their pre-order starts tomorrow and if pre-orderd tomorrow it'd guarantee a phone on Sept 21 whenever you go into the store. With a Radio Shack 5 mins from work I was thinking about pre-ordering it when they open tomorrow and I'd be able to pick up my phone next Friday when they open. As someone on the East Coast, I'd rather not set my alarm for 3am and worried getting it on the 21st if I order when I get up at 6:30. It would be much appreciated if anyone could weigh in.
