Brings parity with Android, Windows Phone 7
Spotlight search will gain more practicality in iPhone 4.0, further investigation into the developer firmware shows. In the v3.x code, Spotlight behaves more as it does in Mac OS X, letting users retrieve local files such as songs and contacts. The v4.0 release adds the ability to search for web results, or specific entries in Wikipedia.
The feature is not original; a similar option exists on devices running webOS or Android 1.6, and it has been announced for Windows Phone 7 for some time. iPhone 4.0 may introduce support for video chat, however, along with officially acknowledged features such as multitasking and folders. Some code references suggest that a fourth-generation iPhone may have flash and a front-facing video camera.
