Scarflash, does this really work now with the latest public software? I have use the internal memory(which should be locked by the security code) of the N810 to store user sensitive data.
By upgrading the software, I've figured out that you can easily bypass it by just flashing the device again. I am not sure if it was a temporary issue or just a feature. From this day on I've removed all my private photos, documents and contacts from the tablet to be sure that this data is not falling into wrong hands.

PB, I hope you did not stored to many user sensitive stuff on the device, e.g. mailbox access data etc.
