Default Solved?

I have a BB 8900 on T-Mobile here in the USA. I had upgraded my BB to .822 and after a few minutes of using the ring tones, they stopped working.

I too encountered all of the problems listed in this thread - but I believe I've found the TMO supported solution (and I didn't see it listed in this thread). I called them several times and finally found a CSR who found a solution in their knowledge base.

* While the BB is up and running, do the three character keystrokes to get the BB to reboot (I think it's alt, right shift and delete - you can Google it).

* The screen goes black. When you see the "Blackberry" logo and the progress bar, IMMEDIATELY re-enter the three character keystrokes listed above

The CSR called this the double soft reboot.

It's been two full days now and all appears to be well.
