A new OS has been leaked for the RIM BlackBerry Curve 8900 smartphone and is the BlackBerry Curve 8900 OS 4.6.1.174, leaked by Vicious Cid of the Crackberry Forums.

As always this not being an official Research In Motion BlackBerry Curve 8900 release, you will install at your own risk.

However if you haven’t installed a BlackBerry OS beta before you can hit up the source for some OS instillation tips and tutorials. Conversely you could just wait until RIM do push out an official BlackBerry Curve 8900 OS update.
