Whatever you do, make sure you don't "get" the update when you are near the Canada or Mexico border where you might unexpectedly hit an out of US tower. The upgrade costs over $100 in roaming charges, doesn't install properly, and the phone won't work properly until it latches onto a US tower again and reloads the entire upgrade. Then, Verizon will argue that the times the phone attempted to upload the program, every 24 hours for three attempts, was you using the data. Thus, you get 3 additional multiple hour download attempts at roaming rates which requires at least 3 hours with multiple customer dis-service agents before one of them finally notices that the "data uses" were exactly, to the minute, the same length and started at exactly the same time every day for three days. After this your bill can be corrected and they will ask if there is anything else they can do for you.
Go ahead, ask me how I know this.......
