11.6 Attention
The central element of Java Security is the private key. If Java Security is activated and you
lose the private key, then the module is destroyed. You do not have a possibility of
deactivating Java Security, downloading of a new Midlet or of starting any other operation
concerning Java Security.
In order to prevent this, we recommend to you particularly to secure the private key.
