Mail - Search = Driving - Left Turns

Let me start off by saying that iPhone is the greatest device I have ever had the pleasure of using. However, having to rely on it exclusively for a week (as my only means of connecting to the world), the only complaint that I have is that the Mail app definitely needs searching capabilities. The good news is that iPhone software 2.0 will bring us this feature, but for the time being it's really painful without it. While we are on the topic of email, junk mail filtering (even a basic one) would be really nice too!
