Even though the phone was available at Walmart a few days ago, now you can get the "Less waiting, more watching" HTC Sensation 4G, directly from the T-Mobile.
You can get it for $200 if you walk into a T-Mobile store (after signing 2 year contract) or online! Just select an appropriate plan to suit your needs.
The phone is snappy and can hold to the T-Mobile's sales slogan. There is a 1.2GHz dual-core Snapdragon processor underneath the 4.3-inch qHD screen, and Android 2.3 with Sense keeping you beeping.
