Finally, as of yesterday, Crackberry is reporting the availability of an official update from Verizon for the BlackBerry Storm while OS 4.6.1.250 was pushed out for the BlackBerry Curve 8900.
Today Crackberry announce a couple of leaked operating system updates for GSM users; OS 4.5.0.153 for BlackBerry devices across the board, and for the BlackBerry Pearl 8220 OS 4.6.0.278.
As usual the required disclaimer; these are not official OS updates and are not supported by Research In Motion or carriers and the user installs at their own risk, and as always backup your data beforehand.
