Glad to see some of you guys took it up as well.
I'm a longtime T-Mobile fan. I know a lot of people don't like it, but I've never had any problems with cell coverage or customer service, and they have great plans.
How do you like the HD7? (Just so you know, the phone can easily be "modded" with the android platform if you would rather use that. It takes about 25 minutes to do, and is very easy to set up. You don't need any technical knowledge. Just search any of the 100 videos on youtube explaining it)
Windows isn't bad, I'm just more familiar with Android so I modded mine. It works great.
