From those serial leakers over at the FCC (when is Patrick Fitzgerald going to start investigating them?), it's the latest Pocket PC smartphone. This one, branded the Kinpo iDo S600, is a GSM model, running Windows Mobile 2003, and sporting a 1.3 megapixel camera, Bluetooth, IR and miniSD. From the looks of it, this is going to be a U.S. version of Kinpo's 5.1 ounce iDo Hydrogen, which the company claims is the lightest Pocket PC phone on the market (the name is a play on the weight; this phone is not powered by a hydrogen fuel cell!). Since Kinpo is a big OEM company, there's a good chance this will come out under another name, though for now at least, all the documentation refers to it as the S600. No word yet on when this is coming out, though we're sure that Bob Novak knows already.
