TmoNews is reporting that HTC's One S will be released on T-Mobile in just over a couple of weeks — Wednesday, April 25th, to be precise. The site had previously reported the same date, but now it's backing up its claims with photo evidence from an internal T-Mobile training document. According to the document, pricing and availability are set to be officially announced on the 16th. It also reveals aspects of T-Mobile's marketing plan for the device — it sounds like the carrier will be placing the One S front and center in its stores, with TV and online advertising set to run until mid-June. "Select stores" will also be displaying the $199 Beats Solo headset, presumably to capitalize on the fact that you'll no longer be getting Dr Dre earphones bundled with your smartphone.
