I understand their need to cap data usage. These days smart phones are using extreme amounts of bandwidth. We're not talking about BlackBerry phones where the data is small, the iPhone streams so much data it's transferring as much as a laptop.
Wait 4-6 months and Verizon and other carriers will follow suit. With the newer smart phones out there the bandwidth will be used so much they will need to cap it.
I would like to see a lower rate plan over some "reward" program. I shouldn't have to pay the same amount as a guy who is streaming Pandora/YouTube 10 hours a day.
