[Every week, we sum up sister iPhone site FingerGaming's top news and reviews for Apple's nascent -- and increasingly exciting -- portable games platform, as written by editor in chief Danny Cowan and authors Tucker Dean, Jason Johnson, Ryan Hibbeler, and Mike Rose.]

This week, FingerGaming covers Disney's Split/Second and the space exploration title Kometen.

Also within are the lists for top-grossing, most-downloaded free and paid Apps from Apple's store, as well as reviews for Skate It and The Iron Horse.

Here are the top stories from the last seven days:

- Top-Grossing Game Apps: Skate It, Zombie Infection Enter iPhone Charts
"Clickgamer’s Angry Birds continues its month-long reign as the App Store’s highest-grossing game app, as PopCap’s Bejeweled 2 and Gameloft’s Iron Man 2 finish at second and third place."

- Review: Skate It
"Skate It embodies everything that made the Skate series popular -- the open-world exploring, the simple interface, the self-creation tools -- everything but the control scheme which has gathered it such a following."

- Review: Kometen
"There’s heaviness beneath the lighthearted demeanor of our tongue-wagging protagonist, but it isn’t heavy-handed. The creators give the player freedom to assign a meaning, or lack thereof, to its world."

- Ubisoft Reveals Prince of Persia Retro for iPhone
"Judging from the screenshots Ubisoft has released so far, the new iPhone port of Prince of Persia (based on the 1992 Macintosh edition) appears faithful to the original game in terms of graphics and level layouts."

"The Iron Horse takes us on a short tour through the ages from steam-powered trains to electric beasts. It’s gorgeous, split-second-reaction gaming which just doesn’t offer enough in terms of content and variety of play."
