Good Idea: Contact Coverflow
Among the features we'd hoped to see in iPhone 2.0 that we didn't: Photo Speed Dial. Sure, there's a nasty hack to get photo speed dial by adding web shortcuts to your homescreen, but it's not very convenient and the photos are very small. TechAU managed to have one of those moment where they think of something that we all should have: Contact Coverflow. We like it because, well, the Coverflow framework is already on the iPhone (you've seen it in the iPod app) and can be utilized by other jailbroken apps -- as witnessed in the jailbreak app AppFlow.
We wish we'd thought of this first. Actually, we wish Apple had thought of this first. iPhone 2.1 anybody?
