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.”
