Congrats!

T-Mo works great even on a cut-down SIM on 64GB Black Amazon N9 (I cut out the first SIM for my wife and got a SIM cutter for mine - both work fine). Stopped by a couple T-Mo stores and they wanted $20 for a microsim. I called T-Mo and they said they were out of microsims a couple months back. Maybe they have them in stock now.

In NY both call quality/reception is excellent as well as 2.5/3.5G data and WiFi Hotspot.

Battery life is MEH but this phone is light years more pleasing than the HTC Androids Sensation and Amaze 4G phones. The interface can be a little laggy but hopefully that's fixed in 1.3. Heck, if an iPhone 3G(S) can have a smooth interface at 600 MHz I think a little optimization could make the N9 fly.

In any case, enjoy the phone!
