Just my opinion: cell providers are f'n thieves-and every chance to screw 'em over is a win.
Now, some facts: this hack will work for D2G, though you need to be in MDM 6x00 chipset (in RSD: main/MA/common/MDM 6x00) and PST USB (settings/USB) the rest of the instructions are the same.
Though, I have only gotten this to work once out of a hundred tries on my Windows Vista 32bit, I was running on XP compatibility mode (under preferences when Radiocomm is right-clicked) and ran as administrator. Mostly though, it will return an error that no device is present when I try to rdelem. I hope you have better luck.
Edit: for D2G you'll need to be on P2K4.
