Given that you've coded the reader to jump to the last page of a thread when a user clicks on it, it might be worthwhile to explore if you can go to the last unread post instead. In phpbb3 it's "htt p://forumurl/viewtopic.php?f=1&t=111&view=unread#unread" where f=1 is the forum number, t is the thread number, and the following tags are what I'm talking about. In vBulletin it's "htt p://forumurl/showthread.php?goto=newpost&t=111" without the forum number. Usually demarqued on thread by an icon beside the thread title, like this on your forum: default vBulletin is like this: default phpBB3 is like this: Thoughts?

We had actually implemented this in previous versions where it always jump to the last post by enabling the "auto-scroll" feature. The problem is based on the crash report this scroll behavior is not very stable and is tend to crash the app or make the UI looks funky. We since then turned it off. We will revisit this later.
