App that locks media/SMS

[TheSippler]

I have a SGS and I am trying to find an app that allows someone to use my phone to call, but doesn't permit them to browse my SMS or media (pics and videos).

I have a lot of minutes on my phone and I don't mind sometimes to lend my phone to my brother to use, but I don't feel comfortable knowing that my SMS messages are available to him to read.

Is there an app that will help me achieve what I want to do?

Etc. Most of them have a lite version too.
