T-Mobile has Father’s Day covered, apparently, with a leaked document showing that every phone in TMo’s inventory will be free on June 19. TMoNews scored what purportedly is a couple of commercial scripts. We won’t know for sure that these weren’t ginned up by somebody with 10 minutes to spare until it happens. But in the meantime, you can start pondering over whether you want to walk out with a myTouch 3G Slide, myTouch 3G, G1, Samsung Behold II, Motorola Cliq XT, Motorola Cliq, or Garminfone (dang, that’s a lot of Android!) in exchange for a couple of years of service, we assume.
