The official firmware of T46G will be available very soon(in one or two weeks). Please download it from website at that time.
After upgrading, do a factory reset to apply all change.

I see the xx.73 firmware is out. Any news if this has fixed the 'muffled' sound on the T42, T46, T48?
There is a 35.73.0.50 and a 35.73.193.50 for the T48G
There is a 28.73.0.50 and a 28.73.193.50 for the T46G
There is a 29.73.0.50 and a 29.73.193.50 for the T42G

I have all three phones in my environment. What is the 193 for? And do these xx.73 firmware fix the sound issues?

Thanks,
Todd
