If you have the Bluetooth menu in the top right hand corner of you screen (alongside the volume and such), just go to that and choose "Send File..."
I have exchanged many files with my 3650 and 12 inch Powerbook.
P.S. Apart from exhanging JPEG images and such, if you send SIS or JAR files to your phone you can install new apps without the Nokia PC Suite, you can also send MPEG4 files made in Quicktime and they will play back on your phone.
