Safari has been on the iPhone since the first version launched in 2007, and has been steadily improved, year after year, version after version, ever since. iOS 6 follows the same, steady, evolutionary pattern, addressing long standing user pain-points like image uploads, and providing parity with features from other browsers, like Chrome's tab sync. It also makes Reading List more robust, and provides an interesting way for websites to alert users about, and move them into, apps.
