locking things like the address book or messages?

Hi, just wondering if this is possible. on my old phone (razr) i used to be able to lock different aspects, like say...the phonebook or my incoming txt folder. is this possible on the 7290?

i've searched but i've been unable to find anything that would allow me to do it.

thanks

Not an option! But, I will say this, just add security to the device...

Go to options / security options / enable...
