IPhone Exchange Inbox is Not Accurate

Email is fairly simple to configure on the IPhone and there is great support on the IPhone site to help you out.  What I want to discuss is the issue with the mail that is displayed.  I have a hybrid setup as most of us may need.  I have an Exchange account which “pushes” email to my phone for work (great feature) and a pop account from my ISP (comcast) for my personal email.  What I have noticed is that my inbox for my work account (Exchange) shows 50 recent messages – sounds ok, right?  The problem is that even after I have moved email using my outlook client to subfolders and cleaned up my inbox to a dozen messages or so, the IPhone inbox still displays any recent messages that once were in the inbox that still exist on the server.  From what I can tell, this is something that will need to be resolved in an update for the IPhone.
