BlackBerry OS 4.5.0.37 Got Leaked on the WWW

If you have a Blackberry 8100, 8300, 8700 or 8800, a new BlackBerry OS 4.5.0.37 software update is now available unofficially. The download link on berryreview has been taken down, but they are sure you can find one easily from a search.
There are some risks in trying unofficial updates though, one 8100 user says, “would not recommend downloading for the 8100 at this time. the ui is horrendously slow right now, especially after a cold boot, and third-party applications /will/ crash the phone. i’m downgrading back to t-mo usa’s current version.”
