Bluetooth = short range communication for using with a bluetooth earpiece, handsfree, or uploding pictures wirelessly to a bluetooth equipped PC.
GPRS - a better way to access mobile online content than WAP.
If you only have WAP on a phone, and not GPRS, then mobile browsing uses a WAP call and is charged at call rate by time.
GPRS (on Virgin) is charged at 30p per day used, or a package of £5 for a month.
I'd be surprised if all but the most basic of phones were not equipped with both.
If it's the quad, them I guess you have the choice of:
Nokia 6303

It does have GPRS, as well as bluetooth, and a 3.2MP autofocus camera, and a FM RDS radio.

The LG Cookie has Bluetooth as well as GPRS, touch screen and accelerometer (shake) control, but it looks like the camera is not as good as the Nokia's (not autofocus) and the FM radio is not RDS.

The KS360 has Bluetooth and GPRS, touchscreen and a slide out qwerty keyboard, but the camera is only 2MP, has FM radio as well.
So of that selection, it seems the Nokia has the best camera, The KS360's keyboard may be a winner if you do mobile email, while the Cookie has a larger touchscreen and better camera than the KS360.
Take your pick!
