As anticipated, T-Mobile took the stage and introduced its latest flagship device courtesy of HTC. The One S will be on sale in a week starting on April 25. In terms of pricing, the One S will be available for the fair price of $199 on a two year contract. The HTC One S is similar to the One X that is going to launch on AT&T on May 6th. The main difference between the One S and One X is screen size and processor type, but the One S is very capable in its own way and should appeal to many T-Mobile customers. It sports a 4.3 inch qHD screen, 1GB of RAM, a 1.5GHz dual-core processor, Android 4.0, Sense 4.0, 8MP rear facing camera, 2MP front facing camera, Beats Audio, and 25GB of storage space thanks to Dropbox. Again, the One S will be available through T-Mobile starting April 25 for $199 on a two year contract.
