HTC is known to leak like a sieve and that hasn't changed in 2011 at all. Which is good if you have an unbranded, unlocked HTC Mozart as you can now flash the official HTC ROM with Mango on it. We must stress, if you have the Mozart on Orange or any other carrier to not do this flash and to remember that this is still taking a risk. The details are as follows:

  • OS Version: 7.10.7720.68
  • Firmware: 2250.21.40600.401
  • Radio Software:
  • Bootloader Version: 4.6.2250.0(129193)

Reportedly it runs pretty well, though GPS still may be flaky. A good tutorial on the process can be found at WindowsPhoneReview. Now if we can just get our hands on the Sprint Arrive official ROM, we'll be happy...
