Cliff here. Just bought the HTC thunderbolt, os 2.2. I am hearing lots of different info on release dates, whether it will be 2.3 or 2.4. I assumed I can dl and then install latest OS, as in flashing firmwear updates. I know my way around MS &Linux pc's, but smart phones are virgin territory. Thanks, in advance, for amy 'hand-holding' offered out there!!!
