The socket may physically withstand the insertion cycles but unless mechanically mounted with through hole soldered pins to take the physical stress of insertion then it will suffer the same fate as the surface only mounted socket in the N900 and part company from the PCB traces.

I flattened the two friction spikes on the plug to make it an easier loose fit in my N900 so if I tripped over the cable it would not rip the socket off the circuit board.

Hopefully those that have disassembled their Jollas may be able to tell us the method used to secure the socket to the PCB.
