The HTC One S will be launching in Europe next week, but it will take a bit longer for the handset to reach the US. A new leak is suggesting that the phone will launch on T-Mobile on April 22nd. TMoNews has the original story, which carries and image that seems to come from an internal TMo employee site that clearly states 4/22/2012 as the release date for the One S.
We saw the One S for T-Mobile pass through the FCC, and more recently saw the phone running an Android build with magenta fingerprints all over it. With the handset remaining mostly identical to its international counterpart, an April release seems more than appropriate. Take it as a rumor for now, though.
