I use to use Opera on my phone and had good luck with it. Opera on the computer I never did find anything that I liked about Opera on a PC.
On my phone, I use to use another browser called Bolt that worked well. Bolt was fasţ and had another app that would set it as the BB default browser which was cool!
With my old 8330, I have since gone back to using the good old BB browser. It serves my browsing needs on my phone for the most part.
