Transfer speed from Pc to Phone

Hi
I just bought a 256 mb kinston sd card for my upgraded a920.
I discoved that the tranferspeed is very slow, It takes me about one minute to transfer a mp3 song of 3-4 mb.
The card specification says that it can tranfer with about 1,6 mb/s.


How I can speed up this transfer?
What is the transfer speed with bluetooth and IR?

I thinking about investing in a bluetooth hub, to overcome the problem.

Regards
Brian
