Unlocked w580i internet

[Nexuria]

I just master reset my phone and opera had to go through some settings stuff. I'd made sure it was set to the orange settings, as well as orange in the java settings.

but it said:

Failed to connect to the internet.

Go to Opera Mini Help with your desktop browser or contact your service provider for Internet settings.

I've got settings from the SE website as well as the orange website and neither work. Would it just be simpler to stick orange firmware on my phone? I'm not really sure about firmware updating, pretty new to this! But I can learn if it'd help

UPDATE: I flashed my phone with the generic orange firmware and well... it seems to have reversed the unlock and made it a T-Mobile phone again >.<! How can I get it back to orange?
