Theres been some software mentioned elsewhere on this forum, such as mobimb and oxygen neither of which detect the prescence of the phone when connected via usb cable from nokia.
So were either waiting for a hack or some software updates to oxeygen and mobimb that can read the phones internal memory (apparently my understanding of it is that the 3300 phones memory is split in two, theres the internal phone memory where the wallpapers are stored and the memory card where applications and music files are stored) there seems to be no way to copy between the two.
Waiting... lol
