T-Mobile hands out press invites to One S event on April 18th

We knew T-Mobile has been planning to release its version of the HTC One S sometime in the near future, but we haven't received any official word on exactly when that desired release date will be. That should all change soon, because we just received invites to a shindig being held on April 18th in which we can hang out with the coveted smartphone, which likely means we'll finally get confirmation on when we should expect to see it available in stores and online. It seems as though the rumored April 25th launch may actually be spot-on, but we only have another week to wait before we find out.
