If you go to verizonwireless.com you can view your data usage. I know it's a moot point since we have unlimited data, but you may be surprised!
In half my billing cycle, I've only used 138 MB of data. I figured with my constant downloading/updating of random apps it would have been more. I suppose I haven't really used any streaming programs too much such as YouTube or Pandora. I'm curious who has the highest usage?
