I think I may have experienced something similar to what you're describing.
I've seen text messages or iMessages appear in the messages window and then all of the sudden disappear when I got to respond or reference back to them.
I've also seen texts appear on my lock screen, unlock it, and the message not being there. Responding to the text from memory and the other person responding proving I'm not going insane.
It's iOS 5.0.1 on and iPhone 4 32gb that is from the iPhone 4 release day.
Heh, I've had it happen too (Like all of my messages to some one disappeared, and then later re appeared. And she had complained of something similar). I didn't think much of it, just thought it was some weird random bug.
I guess it's not so random if it is happening this often with lots of different people.

iOS has a messages limit. It's 15 MB - if you go over it the messages will be automatically deleted.
The best thing to remedy it is to manually delete threaded messages that you don't longer need.
