Messaging stops working on a regular basis & most of the time when typing a message there is a major lag & i can be 3-4 letters in front of what is on the screen & im not a fast typer. I have reste messages & erased all data & i have repaired the phone on PC companion all with no luck

I would suggest that you try to boot your phone into safe mode to see if the problem may be related to any 3rd party app that you have installed in your phone:
