Call forwarding costs a fortune

[haritn]

Guys I have a PPC-6700 Sprint and got another phone from my office. Now it would be nice if I don't have to carry around both phones but still can receive calls made to both numbers. One of easier options is to just enable call forwarding on, say, home phone so all calls go to my work cell phone. BUT it costs 20 cents a minutes on sprint which, to me, is expensive.
Now I was thinking - and this may sound completely crazy, is there any application on PPC 6700 that will initiate a three way call automatically to my work phone every time someone called in to PPC? At least it sounds possible in theory so I though I will just throw it out there and see what everyone had to say !!.
