Bluetooth Connection between Mobile Phone SAGEM my511X and Macbook 2nd generation runnning Mac OS X 10.5.4 Leopard

These two devices can be paired.

In the bluetooth menu on the mac, one can use "Send Files..." to send jpeg etc. but not files of unrecognized types, say, pdf. Sent files appear in the folder "Mes Images," which corresponds to "My Pictures."

It seems that files cannot be sent in the opposite direction. Neither "browse the device" in the bluetooth menu on mac, nor "envoyer par bluetooth" on the mobile work, while the latter works between two mobiles.

(Japanese version of?) iPhoto does not recognize photos in "Mes Images" directory. It seems that it only seeks in "My Pictures". I wonder what determine these folder names. Something like locale?
