Samsung
t309 data cable
T-Mobil sold me serial cable/software for e335/e635. So I could return it I didn't open the software. The download section at Samsung gave me PC Studio 1.0. This software and cable version don't work.

Says PC Studio 2.0 Data Kit PKT130LBEG/STD are for the t309.
Hardly anyone sells this and those that do say it is for the d-500.
