I personally use PocketCM. It lets you scroll just like the iphone through your contacts. Has tons of skins for it that people are constantly making.

For the picture viewer get HTC Album. It takes a little bit to get the hang of it. Like when its zoomed in to a pic. If you dont want to scroll through you have to hit the bottom center of the screen just right. Very clean looking though.
