Limits for other devices not explained
The Panorama feature announced for the iPhone 5 will also work on other devices, Apple has indicated. The option is also being supported on two other devices, the iPhone 4S and the fifth-generation iPod touch. It's unknown why other camera-equipped devices, such as the iPad, are unsupported despite Panorama being built into iOS 6.
To use Panorama, a person taps the shutter and pans horizontally across their field of vision, up to 240 degrees. The resulting image can be up to 28 megapixels in size.
Apple regularly reserves some iOS features for its latest hardware. The best known example may be Siri, which was initially restricted to the iPhone 4S, but will be coming to the iPhone 5, third-generation iPad, and fifth-generation iPod touch when iOS 6 arrives on September 19th. Hackers have proved that the technology can run on earlier devices, fueling speculation that Apple is trying to boost hardware sales and/or limit Siri traffic on its servers.
