on your PC, set up two 'dummy' jpgs. eg DSC1000 and DSC5000

Copy the 1000 one to phone A and the 5000 one to phone B.
(you might delete all other pics first...)
Then, as long as the format of the names is correct, the handset should
increment the numbers in sequence - then, the trick is, when you clear the
memory card, delete all the previous pics EXCEPT the current highest - that
way, you preserve your sequences..?
