Re: Lots of people test? This is going to vary in every major venue. AT&T has contracts for cell exclusivity in some stadiums and Verizon has it for others. It just depends where you go. In Texas AT&T rules the roost, but in the northeast I'm sure Verizon is king of the stadiums.
Didn't have any problems texting or calling my iPhone buddy who was at the UT/Baylor game today.
