Hi all.
Is there a way (built-in or 3rd party app) to backup & restore the internal
memory of the phone to a file on the flash card?

This way one could then backup/restore easily the phone on any computer
(and Linux, virtual computers, ...) without the cumbersome SE PC Suite, as
the flash card is seen as a flash disk anyways.

In summary:
to backup: backup ram to flash file -> copy flash to computer
to restore: copy backup from computer to flash -> restore flash file to ram
