An FCC filing from June promised that the HTC Flyer would be headed to T-Mobile, but the tablet never surfaced for the magenta network. No in plain sight, anyway. T-Mobile has apparently been offering the Flyer to business customers for the past few weeks, but sales have opened up to all through HTC’s website. T-Mobile’s site still doesn’t list the tablet and no official release announcement was made, which is odd. But for the moment it looks like all interested parties can get their hands on the Flyer for $299 on a new contract or for $454 without.
