We're looking at possibly replacing our Treo 650 units with the Treo
680. But there's one particular undocumented feature that drives us
crazy - the way the device goes into sleep mode immediately after
hanging up from a call, or at other inopportune times. Cingular/Treo
support tell me that this means the unit should be replaced. But from
talking with other Treo users, this is apparently common.

I just want to be sure that the 680 isn't going to do the same thing.
Anyone have that problem with the 680?
