In this video I give a complete overview of iOS 4.1 for the iPhone and iPod touch. I cover the Game Center, Ping support, HDR photo capability as well as a word of warning about jailbreaking the new firmware. iOS 4.1 will be a free download for the iPhone 3G, iPhone 3GS, iPhone 4, iPod touch 2G and iPod touch 3G next week.
