Is it possible to have a different password for installing app on BB?

I am going to loan my BB to a friend and I do not want him to install any apps.

Is that possible to restrict that? How to set a different password so if he tries to install app, he will not be able to?

Thanks.

If you can trust your friend with your PB, is it really a good idea to leave it with him? Tell him to not do it, and if he does you curb stomp him. :devil:

Assuming he will actually want to set his email up, send texts etc you are probably better doing a full backup of the phone and doing a factory reset on it so he has a "new" phone to use.

When you get it back simply wipe it and restore your backup.
