buying usb bluetooth dongle

[Zoran Kolic]

Howdy!
I would like to hear opinions about bluetooth
dongle, I have an intention to buy. The list in
stores in my area is not so long.
 - canyon btu4
 - gigabyte bt03d
 - msi star key 2.0
Does it make any difference, since I cannot get
the name of the chip inside the product?
The primary goal of this dongle should be to
get/put data from/to cell phone (nokia 6233) and
it's memory card. I found references to products
like obexapp and gammu. What is the prefered way
to do the job?
Best regards
