New OS for Diamond ?!?!

[abspade]

I had to replace my touch diamond after going for a swim. I loved the original. But now I have this new Operating System that sprint has on here. One of the many issues is that While Texting, if someone texts me multiple times, and I go to that screen, (in thread mode), it doesn't mark all messages as read, even after I reply. The old phone would do that. Anyone have a quick fix for this?

My phone also has this new "slide to answer" function (i presume stolen from the iphone).

Please help! Thanks!
