with the attached patch it is possible to use ObexFTP with newer Gigaset S(L) class DECT Handsets.
I did some tests with Gigaset SL78H and Gigaset S79H over USB without any problem. There is a report that the T-Sinus 501 Handset (which is an OEM Gigaset S68H) is working too <http://www.ip-phone-forum.de/showthread.php?t=212640>
git patch against git://github.com/zuckschwerdt/obexftp.git
Wow, finally added to repository on gitorious.org/obexftp
