Audiovox SMT 5600 / SPV C500 (HTC Typhoon)

Hi All,

I bought this fine phone back on AT&T. I have since switched over to Cingular and have unlocked the phone and used the info on the 'net to change various settings which enable its use on the Cingular network.

Now that this phone is available under the Cingular nameplate, I would like to find and apply the Cingular version of the phone's firmware.

Does anyone know where I can get the Cingular version to be applied to the phone?

Thanks!
