SMS list resets when powering off/on and doing iOS updates

Hi everyone,

I seem to have a frequent problem with my SMS list changing/resetting every time I turn my phone off and on... and also when doing iOS updates.

Every message in my SMS list gets changed to the date and time the phone is turned back on or updated. This happens EVERY TIME and makes it difficult and very frustrating to view recent messages.... as they can be anywhere in the "newly dated" list.

Does anyone (or Apple themselves) have any advice or a solution to this problem?

Thanks,

Cheryl
