I assume the System Wipe isn't this thorough, but I can't find any information on Google or the FAQs on what kind of wipe it is. Is the Jl_Cmdr a more secure option?
See RIM paper at Deleting all device data from the BlackBerry device memory
"If content protection is turned on, during a security wipe the BlackBerry device uses a memory scrub process to overwrite the BlackBerry device flash memory file system. The BlackBerry memory scrub process complies with United States government requirements for clearing sensitive user data, including Department of Defense directive 5220.22-M and National Institute of Standards and Technology Special Publication 800-88."
Looks like 5220.22-M is only valid if Content Protection was enabled on the devices.
