iPhone Mixing Old Text Messages to New Text

[innesd]

When I have a fairly long text, my iPhone 4s is overwriting the end of my text with random parts of old text messages. Obviously this is getting embarrassing.

Rough guess,you have never deleted any texts?

If the answer is yes, odds are you have a partial database corruption from the sounds of it. Which means you may need to finally delete everything and start over.
