I'm so glad TS is finally available on Market! I would do my best parcicipating with my suggestions and reports.

Ok, so I'm using HTC Desire with 2.3 on it.
Crashes:
The most annoying and the only one crash is when I'm back from the stand by mode, I have to reconnect to the server.

Suggestions:
1. A click or pop sound when a person connects/leaves to your channel.
2. Private message system is a must!
3. PTT with off screen like default "volume up" button.
