I have hundreds of images on my mobile right now and want to transfer them via bluetooth to my PC running Windows XP.
I don't have a data cable or a bluetooth adapter.
How do I transfer data from mobile to PC?
Without an adapter your PC simply cannot do bluetooth. This is a hardware problem, not a software problem.
You can buy a USB adapter for fairly cheap, which will come with all the required software to use it, and should interface fine with any bluetooth device.
