Not sure if anyone's seen this, but it was on Engadget Mobile...

Apparently Sprint's last Mogul software update -- version 2.16.651.0 -- ruffled a few feathers by unintentionally introducing new Bluetooth problems as part of the release. Sprint and HTC's advice? slip on back to version 2.09.651.3 (hit the read link to grab it) until another update is released at the end of November. The unexpected treat in all this is the announcement of HTC's efforts at developing a separate update that will include both GPS and EV-DO Rev. A, awesome! Keep an eye on these pages for more info soon.
