[Staffslug] Eee PC & GPRS connectivity

Hello everyone I'm thinking of buying an Asus Eee PC, but I need to be able to use it for GPRS connectivity (with O2). I was thinking I could buy a bluetooth dongle, then use a Motorola Razr as a modem. Does anyone have any experience of this? if so, does it sound easy enough to do? Also, will all bluetooth dongles work with Linux? If not, can someone point me in the right direction of a compatible bluetooth adapter. I would describe myself as 'in between learner and intermediate' with my Linux knowledge. Cheers Al
