Re: Fash cards sanitization from Nokia Symbian and WM5/6

In the case of blackberries it should be noted that only the lowest  
security classified information is allowed to be accessed. This is the  
case in Australia for government use. For that level of assurance the  
blackberry provides sufficent data security.

The best advice i have would be to contact the manufacturer and ask  
what their internal wiping process does unless you have access to your  
own facilities to conduct this type of evaluation.  And then run this  
process many times to achieve a wipe.
