How i delete my iphone 4 conversation

Try deleting a few texts at a time until you bring the number down to something more manageable.

When you first go into messages, slide across your husbands name & it should say delete, click on that & it should do it? Reboot your phone if it freezes by holding home & sleep/wake button at the same time, don't do anything when the slide to unlock thing comes up, just keep holding then it should turn off then let go off JUST the home button, keep holding the sleep/wake until the apple logo comes up then you can let go. :) Hope it helped.
