iOS 5 turns Japanese iPhones into earthquake alarms
Following the devastation wrought by the recent Japanese earthquake, Apple has hooked the country's early warning system into iOS 5. The tectonically-volatile nation has the most sophisticated alarm in the world, delivering life-saving warnings seconds or minutes before disaster strikes. iOS users already had access to this functionality via apps like Yurekuru, but iOS 5 will bring it directly into the operating system. The service can be activated in the Notification Center settings pane, accompanied by a warning that the constant connection will deplete your battery faster -- a fair exchange if it saves your life.
Video of iOS 5 on an iPhone 3GS and a 4 side by side
The folks at AppleRumors Italia did a side-by-side video comparison of iOS 5 on both the iPhone 3GS and the iPhone 4. As you can see in the video, the two models perform similarly with only a small amount of lag apparent on the iPhone 3GS during certain tasks, like loading a complex web page. The biggest difference is the lack of some features, like HDR and photo editing, on the older iPhone 3GS. Though this is only one video, the results are encouraging for those still rocking a third-generation iPhone.
