Think the iPhone has made an impact on the market already? You've got that right. Check out this little contact application that claims to use "iPhone style" scrolling.
"iContact is a simple contacts applications for your Windows Mobile device which will help you scroll your contact list in iPhone style by sliding down your finger in the screen ! It's really amazing and if you get used to it iContact could be one of your everyday apps. The app is very basic, it only lists contacts in scrollable list. I use it for accessing my contacts by scrolling the list with fingers, similar to iPhone. Just tap, drag and release. To select a contact, just tap and release, and standard contact details dialog should appear."
