i have a 6600 and a week ago i bought a usb bluetooth (as the maid stole the irda) but i was very dissapointed when i saw that i couldnt send my pics to the pc.When i try to directly send to the pc the fone says Unable to connect . i installed nokia pc suite and oxygen fone manager to resolve to problem but neither worked as when i tried to create a serial port connection it says that remote host cancelled connection.

Waiting for your suggestion

Maybe you should try to pair ur PC to phone first

Before using pcsuite or oxygen you must connect phone to pc and this is your real problem.
You must search phone with pc and make pairing of devices, when they are connected you can autorize pc connection on your phone, so you don't nedd to make pairing everytime..
try it
