Well like I said, I havent ran across but a couple times where I needed to go back and read something, so actually being able to read it all isnt a big deal but the other day for instance I had one conversation that got to be over 150 msgs long, and the scrolling definitely sucked, not to mention I had 2 other convos going at the same time. But I say atleast as long as You have the main messages screen just show the first msg of each convo, then the next line saying how many more there are (like the gv inbox page) and the the last two messages, how ever you decide to implement reading the rest if at all would be great.
