Novell begins shipping the 1.0 edition of MonoTouch, its commercial software development platform that extends the .NET Framework and the C# language...to Apple's iPhone. Although this effort is itself an extension of Mono, the open source .NET extension for Linux and Mac that's funded by Novell, MonoTouch is somewhat different: First, it includes an exclusive, Mac-based development environment for iPhone. Second, it requires the iPhone SDK, which means MonoTouch is being marketed for registered Apple iPhone developers. Third, it ain't free -- a five-developer license costs $3,999, reports.
