there are no official 6.5 roms that have been released by a carrier for the TP. The ones that are available have been created from builds taken from other devices and are available in the upgrades section of this forum as raid said. I recommend trying demolition, raidzero's, chaostheory or mightymike roms, all are great roms and each one has something different to offer. Take a look at the stickied thread in the upgrades section about how to unlock and flash for a quick how to, there is also a sticky in the general tp forum with a video tutorial.
