This isn't strictly related to the PPC6700, but you guys are so helpful!

Does anyone know of a program or way to have another cell phone number forwarded to my ppc6700 number and me be able to differentiate when a call is coming to my 6700 or being forwarded from the other cell?

I have two phones with two separate phone numbers (one for business), and I would very much like to only carry the 6700. But I can only do this if I know when a call is coming in for business as opposed to personal.

I know there are call forwarding services out there, but I don't need another phone number and I'm not sure if I will be able to tell which phone number the caller dialed.
