I originally bought a Verizon iPad2 last week giving up hope that I would ever find an AT&T model in stock, but lo and behold this morning I was able to snag a 64GB white AT&T model at my local Apple store in Peoria, AZ at Arrowhead Mall. I was about 50th or so in line and got really lucky!!! Thats besides the point. Since I have both models I figured I would post some real world test results. These test were taken in north Phoenix. The first test was inside with AT&T having only 3 Bars and the second is outside with 4 bars on AT&T and full Bars on Verizon. Looks like AT&T is a winner for me. Sorry if a post like this already exists. Let me know what your results are if you also have both models and live in a different area.
