It is a 3GS which I bought as it was on a bargain contract. Equiv to 31USD per month including handset, calls and 300MB of data (24 month contract). This was the same rate that I was already paying for my old nokia 6220C which was just out of contract. The cheapest N900s are 2-3 times as expensive and I find them a bit too chunky.

Looking around there is a usb ethernet module that I may be able to compile to get it started.

I'll start hunting around some other linux forums to find out some command line examples of pairing and see if that helps.

Cheers,
John
