OK, Apple answered my question:
http://support.apple.com/kb/HT2110?viewlocale=en_US&locale=en_US
* Devices that support hardware encryption: Erases user settings and
information by removing the encryption key that protects the data. This
process takes just a few minutes.
* Devices that overwrite memory: Overwrites user settings and information,
writing a series of ones to the data partition. This process can take
several hours, depending on the storage capacity of your iPhone or iPod
touch. During this time, the device displays the Apple logo and a progress
bar.
So now the question remains: is just moving the keys good enough? Is there
any way to recreate the keys, or is iErase the way to go?
