Was talking with the T-mobile tech support rep (after learning the Vibrant does not support UMA to use wifi calling at home) and she told me about the upcoming back to school sale where many phones are free, and even better, adding an extra line is FREE till 2012. Not an extra $5/mo., free. Quite a few decent phones are available, too. Very cool, thought I'd give you guys a heads up. I might even get a phone just to for a back-up.
