Kingdoms iPhone is a server specificity designed for compatibility with the iPhone. Kingdoms iPhone is currently under development, but will be able to be accessed via a special version of the Mac Graal client only available for the iPhone.
Kingdoms iPhone, as well as all iPhone servers, runs a specially modified Mac Graal client. The client runs off the same engine as normal Graal clients and is able to execute GSscript2 code. This means that it is possible to develop content for both the iPhone client and the normal client at the same time using the same tools normally used for development, such as the level editor, Remote Control, and Graal Shop.
