I am using B6V10 (167 radio) but Operamini 5.0 is not working on that??
Make sure you select: "Download Opera Mini 5 Beta for Blackberry anyway"
I'm running the same OS as you and that is exactly what I did and it works perfectly.
The only other thing I can think of is that your details state you are on 188.8.131.52. The base OS for Beta6v10 should be 151.
Maybe that makes a difference.
On 9530 184.108.40.206 OS works great!
Woa, mine is working great!!! I pulled a batter
Thanks all of you
