Separating Business from personal calls on a cell phone?

[Thetech]

I have a small business and a Blackberry Curve,
I would like to be able to distinguish business calls from
personal calls.

I thought about call forwarding but someone told me you
see the number of the caller, NOT the number that calls are being forwarded from.
I don't want to have to carry two cell phones.

Anyone know any work arounds for this?

Google Voice maybe, when it goes wide release. Ive been using it since it was Grandcentral.

Charge all the calls to the business. The IRS doesn't know you have no personal phone!
