Apple has just released the very final version for iOS 4.1
for iPhone 4, iPhone 3GS, iPhone 3G and iPod touches. This version of
iOS brings a number of new features for iPhone and iPod touch users
including: Game Center, HDR Photography
for iPhone 4, iTunes Ping, HD video upload on YouTube and MobileMe for
