changing setting from keep forever to 1 year
Hi I currently have my setting for my iMessages App to keep messages Forever. Why I thought this was a good idea is beyond me. Is there a way to keep messages I want (I am willing to go through and delete threads that I don't want) and change the setting to 1 year or 30 days without deleting these messages I want?
