I was just being curious looking through the iPhone filesystem, when I ever casually came across references to the following: RADIO (com.apple.mobile.radio) - Please Register or Log in to view images Keyboard (com.apple.purple.KeyboardDemo) - Instore demo app? Converter (com.apple.unitconverter) - Probably for converting eg. km to mm Business (com.apple.widget.phonebook) - ?? Translator (com.apple.widget.translation) - Probably a laungauge converter The references to these application can be found in: /System/Library/CoreServices.app/Springboard.app/English.lproj/LocalizedApplicationNames.strings on the iPhone file system. Hopefully, we'll see at least a few of these in a future software update.
