It's a windows XP. I have a Motorola rokr and its got bluetooth but i doont wan to have to get a memory card or usb cable. is there any way i can get bluetooth on my pc for free?
No. Bluetooth requires specific hardware in your computer. It's not software that you can download for free. It would probably be cheapest to get a memory card or USB cable, because then they can be used if and when you get a new computer.
What i did was i bought this little usb stick which was a bluetooth stick it cost me like 20dollars i forget where i got it from, but they are cheap to buy. Its really easy to install cuz all u do is stick it into the computer and your computer has instant bluetooth
