Wanna have a shot at getting a 3G iphone without having to wait on line for the model you didn't want? Top Muffin has the "iPhone3G Store availability tracker" which updates its page based on Apple's JSON feed. It looks like it works pretty well but the proof is in the pudding.
It might be worth a few extra minutes to give a call to you Apple store just to double check in case
