We're hardly the first people to complain about this, but it drives me nuts. I rarely delete messages (for better or worse), so I have an ever-growing iMessage database that is basically inaccessible to me. I don't know why I pay to back up 20 gigs of messages that I can't even access, but here we are. For instance, I wanted to figure out the exact date I met my partner. The only way to do this on iMessage is to scroll up...all the way up. With a few seconds of god-knows-what in between every page. The endeavor is usually futile, though; because when you get a ways back, the iMessage app will crash.
