text message lock

[PPCFreak]

so how about a pin code on the lock screen of the entire phone....?

This would help keep prying eyes out of the entire phone.

This only works when the phone had been booted...on a restart the phone is unlocked so no pin to enter.

From a quick google search, XDA had similar questions:
Password Protect SMS/ MMS - xda-developers

Seems most of them in the link above go no where.....

I don't use any of these but did find this one in a couple of M$ chat sessions on the subject.

Here is maybe a better one:

Not free but if your looking to keep secure, only $20.

This is one I used for a bit but took off after I got tired of the password....it does what it says....and its free and if you have issues can post on XDA what your issues are.
