We have yet another leakage of a BlackBerry OS today courtesy of CrackBerry, this time round it is BlackBerry OS 4.6.1.231 which is for the BlackBerry Curve 8900 smartphone.

Apparently the word is this OS update is quite a step up from any previously leaked BlackBerry Curve 8900 OS, thus Curve 8900 owners may wish to give it a try out.

As with all things unofficially and leaked comes the usually disclaimer, this is not an official OS update and therefore not supported by Research In Motion or your carrier so install at your own risk.
