SourceGoogle Chrome is one of the world’s most advanced and popular web browser, used by millions of people around the world on desktop and notebook computers, as well as mobile devices running the Android OS. Until now, users of the iPhone, iPod touch and iPad had been left in the dark in terms of an official Chrome release, and instead had to settle for Apple’s Mobile Safari or other alternative browsers on the App Store.
The req's include iOS 4.3, so iPhone 3G and below and iPod Touch 3G 8GB and below are all unsupported.
Also: Google Drive is out for iOS, joining Google Chrome. @yusuo Thanks for confirming!
