Ok there have been WAY too many people that have misconceptions about the data usage on their phones.
The $30 plan that you got to surf the web and to play with your apps. This plan includes "UNLIMITED" data usage. It does NOT have 5GB cap. This has been confirmed by 3 verizon reps on our site. Also confirmed if you read the terms and conditions of the data plan you purchase. The terms and conditions can be found on their website, or below this paragraph.
The 5GB data usage plans are for following and ONLY for the following: USB Modems, PC Cards, ExpressCards, MiFi 2200, Notebooks, Netbooks, OR if you are tethering a device from a: Mobile Broadband Connect-capable smartphone or blackberry. Shown in the PDF file below.

On your Phone as long as you are using it ONLY as a phone to access the internet, play games, listen to the radio, or whatever else the phone is capable of (NOT TETHERING!) it is unlimited.
*WARNING* If you do find a way to tether the phone without paying for it, verizon wireless has the ability to find out that you are doing it. While it is unlikely that they find you if you stay under 5GB, they still have the ability to. They will charge you the full amount for the data usage for the times you've used it if caught.
