Hey guys and gals, I'm extending my current phone plan which allows me to pick a new phone. I've decided to go with the HTC Desire. Now I've added an internet plan to go with the whole deal, so I can have the web on my phone when I'm out. However, it won't activate until my new plan kicks into effect (which is a few months from now). What steps should I take to insure my Desire won't go on the internet outside of using Wifi spots in the house or in places where available?
