I have been using a BB 7280 thru Cingular for the past 18 months or so and am looking to upgrade to the 7100 series. In doing some research I have found a couple of websites offering free 7100g's and/or 7105t's. Does anyone have any experience with wirelessbuy.com or letstalk.com. How can these companies offer the devices for free when Cingular and T-mobile want to charge $199. In addition, does anyone have an opinion on T-mobile vs. Cingular for someone who travels nationwide.

I appreciate any feedback.
