Following up on Dubdub's question, I did some searching, and what little I found dealt with OS 6. And see
RBHybrid's 9700 v3.0 (5.0.0.743/862/5.2.0.9/6.0.0.31/.135/.141) - Page 2 - BlackBerry Forums at CrackBerry.com, which I take at face value.
I can't explain what happened, but I wonder same as Dubdub if that app is maybe not for your OS version.
