Info: Virgin Mobile, LG VM510 Rumor Touch, app question

Specifically, and I have to apologize because I am new to forums and the like, I am trying to find an app that is compatible with my Rumor Touch that will hide certain files on my phone, password protect certain files on my phone, password protect SMS inbox/contacts on my phone . . . something of this nature. If this has been covered here, I could not find it and I apologize for wasting everyone's time.

I have Googled these phrases, and been to the ultra-helpful articles about jailbreaking the rumor touch and how to install 3rd party apps. I cannot seem to find an app, jar or jar and jad both (and I do have jadmaker), to install that fits this bill.

Does anyone have any advice? Thank you in advance.
