The T-Mobile MDA is the USA version of the T-Mobile MDA Vario also known as the HTC Wizard, Qtek 9100, and i-mate K-JAM. PC Magazine has published a review of this new device on their website. It should be available through T-Mobile USA on February 20th for $399 with a new contract. That’s a pretty good deal, I’d say. Also of interest is PC Magazine’s review of the T-Mobile SDA which mentions a new $30 per month T-Mobile unlimited EDGE and WiFi internet plan. Previously, the Unlimited EDGE and WiFi add-ons were $19.99 each.
