You don't have to hide the phone type from T-Mobile. I took mine down to one of their stores when I got it a couple of months ago and signed up for the Even More Plus and added the Unlimited Web for $10. Since I didn't have one of their phones they just grabbed a sidekick out of the drawer and scanned it, then called into customer service and told them it really wasn't a sidekick and it was an unsupported phone. I get 3G & 3.5G at my house. I just ran mobile speed test and got 1826, 2128, and 2083 kbps download speeds using 500kb,1 mb, and 2 mb files. Not too shabby!
