There are several products that do this, some are better than others, or said a better way, they all seem to have their little quirks.
The first device I purchased (Several Years Ago) is called a Cell Socket. It actually connects directly to the phone and can interface with several different phones as well. (But it takes a different one for each brand of Cell.)
The latest version (WHPWIRELESS Model 5161N) that I still use with my Antique NOKIA 6190 (At times) gave caller ID and recognized switch hook flash to answer a Call Waiting Call. Once in a while however, I have to re-seat the phone in the cradle to make it work. When I really want to use it, I make sure it will ring through by making a test call.
The Next one I tried was a BLUETOOTH Device, which is handy, called "Dock N Talk A 100 with Bluetooth Module Bt01".
Well, I couldn't get it to work correctly with my Iphone. I spoke with their tech support and they informed me the VERSION of Firmware wasn't new enough, and I would need a BT02, instead of the BT01 to work with my Iphone.
So, I sold it to a buddy, and he uses it with his RAZR.
The last one I bought was a "PMC U118 Bluetooth Cellular Gateway". It works with both my Iphone and my new SIDEKICK 2008.
It has limited capabilities, (No Call Waiting SWHK Flash). However, I also spoke with their support folks and they assured me they will be coming out with a "GEE WHIZ" version later this year.
There are a couple of more brands out there I think, but I have not looked at them.
