iOS (Jailbroken): Chrome for iOS is quickly becoming popular and subsequently it's getting tweaked a lot by the jailbreak community. One of the newest tweaks is BetterChrome, a simple little hack that adds social sharing and homescreen pinning.
With BetterChrome installed, you can instantly share sites you find in Chrome directly to Twitter, Facebook and Google+ by tapping on the icon to the right of the omnibar. You also get the option to save pages to your homescreen as icons that will automatically open in Chrome. This feature has been in Safari since the first version of iOS, but if you find yourself using Chrome instead, it's handy for those sites you have sitting around around on your homescreen. You can find BetterChrome in the ModMyi repository in Cydia.
