I just successfully turned my Cingular 8700c into a Cingular 8707v! After reading the DIY sticky in this forum and having taken off the housing to clean a few times, it only took about 10 minits to do.

Unfortunatly, the 'NUM' and 'CAP' keys are a little stiff and the 8707v DOES NOT fit in the OEM plastic holster. Apparently it is a bit wider than the 8700c at the bottom so it doesn't go all the way into the holster and snap into place. Looks like it will be riding in my pocket for a while until I can get me a leather case.
