What you write to is **NOT** the same eraseblock that previously held the data.
Your information can still be recovered from the "idle pool" of erase blocks on the device.

But it will also do just what it says - blank the entire device.
Which can be a PITA to recover from.

Heh, yes, I can imagine.

If I understand correctly (HAH!) the personal information re login and One Click purchasing is on partition 3 anyway, not partition 4... right?

Reset Device looks like it clears things out, but is no better than a "quick format" from the partition 4 perspective.
