AT&T sent out emails to customers today which reveals that they are limiting iPhone sales to "one per person":

There's been no official word if Apple will be similarly limiting their sales, but it may be a safe bet. Appleinsider reports that Apple Stores are preparing by requiring some employees to stay overnight on Thursday night to prepare for Friday's launch.

Finally, we've heard that some above-average size Apple Stores may be getting on the order of 1000 iPhones for Friday's launch, with a ratio of inventory being heavily skewed towards 8GB iPhones over 4GB iPhones at approximately a 4:1 ratio.

MacRumors forum members are meeting up at their respective locations to stand in line.
