I have my texts stored to the Mass Memory. Every time I connect up to PC Suite and backup it changes it back to the phone memory.
yes its a bug, i think its fixed in the new upcoming v20 firmware, what it should do is when you plug it into the pc it chamges to phone memory, then when you unplug it should change back to mass mem, it has to change as mass mem wont work when its plugged into the computer, i heard its fixed so we shall see the weekend when we all update to v20
