Does anyone know if data cables for the wired GPS for the Treo 600 also charge the phone? It appears that this might be true from other posts, but I couldn't tell for sure.

If yes, I hope that the 650 will work the same way. It would be great to only have two cables: car to receiver and receiver to phone.

I tried to ask a saleperson at about this and the response was "There is no Y-cable for the 650. Please check back in mid-March." Uh, yeah, I know that...

I then sent another email asking about the Treo 600, but I was ignored.
