I know the exact reason why some people think there is a 5 GB data limit and others do not. In January when i started my contract with vz i set it up online. It LITERALLY said that there was a 5 GB/month limit on the droids data plan when i set it up. Now it appears that vz has changed that, but a lot of us took note of it when we signed up because we were kind of disappointed. I know I was afraid of going over my 5 GB limit and getting charged ridiculous fees.
...visit the verizon site and read the (surprsingly short) agreement, you know, the one you signed off one when you signed your contract with verizon.
Ironically, the reason some of us thought the data was limited is because we DID pay so much attention to the contract we signed
