Re:Remote wipe requires remote signal, yes? (Score 1)

Blackberries specifically have additional features that can trigger a wipe if the device fails to check in within a specified amount of time. While this could at least be delayed by pulling the battery, you better not power it up later in a shielded lab or it will nuke itself first thing. To deal with that potential, they would have to treat all devices as potentially having that feature and would need to leave them powered off and deal with reading the date directly out of the device memory. Blackberries (if configured to do so) encrypt the device memory with a key protected by the users pin. A wipe of the device first nukes the key and then actually does a secure erase of the flash memory also (takes ~90 min).
