The iPhone is a big deal right now. Apple just released their iPhone OS 2.0 upgrade, launched the iPhone App Store, and today rolled out the iPhone 3G. Courtesy of Techcrunch’s coverage of the App Store launch yesterday we were able to see that iPhone owners were going ape over Super Monkey Ball. The top applications sales were in fact primarily games. Mobile games are popular, and the trend obviously carries over to the iPhone.

As with most mobile game developers these iPhone app publishers are receiving revenue from the sales of the apps less the 30% that Apple takes for itself. Mobile game advertising company Greystripe would like to help bolster their revenues though with todays announcement of their iPhone SDK release in conjunction with Apple’s moves this week. If you are a mobile game developer you will definitely want to check out their iPhone SDK and their AdWRAP technology in general if you haven’t already.
