What is the best bluetooth home phone device?

How can I initiate a phone call from an iPod touch device, via Bluetooth, to be dialed on a cell phone?

• There is a standard Bluetooth profile (i.e. a portion of the Bluetooth protocol) for initiating phone calls.  Five years ago I set this up on my Palm VX device and my Motorola V360 cell phone.  I tapped a phone number on the Palm, and my cell phone would dial it. Back to the future:  Apple has disabled this capability on the iPod touch.  Has anyone figured out a way to break in and modify the Bluetooth stack on iPod touch?

• Answer:

  To be clear, Apple has not "disabled" this capacity on the iPod touch so much as they simply haven't enabled it. There are well over 30 http://en.wikipedia.org/wiki/Bluetooth_profiles that have been defined by the Bluetooth SiG; the iPod touch includes 6 of these (see http://support.apple.com/kb/HT3647). You would likely need either the http://en.wikipedia.org/wiki/Bluetooth_profile#Phone_Book_Access_Profile_.28PBAP.2C_PBA.29 or the http://en.wikipedia.org/wiki/Bluetooth_profile#Serial_Port_Profile_.28SPP.29 to provide support for remote dialling in this manner, depending on your target device requirements. It seems to be possible to support additional profiles through jailbreak applications on at least some device models, and apps are available that add features such as the http://en.wikipedia.org/wiki/Bluetooth_profile#File_Transfer_Profile_.28FTP.29 and http://en.wikipedia.org/wiki/Bluetooth_profile#OBject_EXchange_.28OBEX.29 profile, but I'm not away of any off-hand that provide PBAP or SPP.
