To browse files on a cellphone use the command to gat folder listing (in my case it is in XML format):

tvrtko@tvrtko-laptop:~$ obexftp -b 00:15:B9:9D:40:39 -c / -l
Browsing 00:15:B9:9D:40:39 ...
Channel: 16
Connecting...done
Sending ""... done
Receiving "(null)"...\

(folder listing here)

Disconnecting...done

And now, to download your newly taken photo you need to type command similar to this:

tvrtko@tvrtko-laptop:~$ obexftp -b 00:15:B9:9D:40:39 -c /Pictures -g Photo-0062.jpg
Browsing 00:15:B9:9D:40:39 ...
Channel: 16
Connecting...done
....
....

For uploading files use this command:

obexftp -b 00:15:B9:9D:40:39 -c /Pictures -p Photo-0063.jpg

NOTICE: Use right addresses, folder and filename specific for your cellphone
