Mobile operating system Symbian has made the move to become fully open source.
In other words, the entire code will be freely available for anyone to fiddle around with as and when they wish, and to use how they wish.
This development has actually been coming since 2008, when the Symbian Foundation first announced its intentions.
The theory is that assorted folks tinkering with and developing Symbian will lead to innovation at a quicker pace for the OS.
Google’s Android OS is also open source, although according to a spokesman from the Symbian Foundation, only a third of the code base is actually open (so reports the Symbian-Guru website).
