iPhone 4S pre-orders start at 3:01 a.m. ET tomorrow morning, which carrier to choose?

We’re not huge fans of the 3:01 a.m. ET pre-order that Apple has put up but it is a good way to make sure the hardcore get the first swipe at the iPhone 4S.

For the first time, US iPhone users will have a choice of three carriers with which to choose from. Obviously, the number one concern is if the carrier has good service in the area. There are some differentiators however:

1. Sprint offers an unlimited Data Plan (Through October).
2. AT&T’s GSM network will allow faster 14.4 Mbps (theoretical) data speeds and talk and simultaneous data and more international roaming options.
3. Verizon and AT&T have free hotspots on their 4GB and up plans while Sprint’s is $30/month.
