Hi Dennis,

Although new(er) phones do have a USB interface, at least some Nokias have Fbus / Mbus connection pads on the PCB, usually under the battery.

As Bill says I think the operative word here is in-built modem; that would definitely be required.

Since you are specifically interested in the 1208, just do a google for Nokia 1208 and fbus; should yield a lot of results.

Regards,

Anand
