To make opera your default browser this is the reg key, for easy installation I would suggest editing the CAB itself so it makes the reg change when you install the CAB instead of manually setting it each install.
HKEY_LOCAL_MACHINE\Software\Microsoft\Shell\Rai\: DEFBROWSER
"0"=Opera Browser
"1"=\Windows\OperaL.exe
Just change OperaL.exe to whatever the name of the opera mini 5 executable's name is.
And that's funny to hear that ya'll pick a ROM and use it across the board, but thanks for that
Already working on and planning the next update. The next one will fix some ruff edges (visually) and I have a few app updates and a couple new things as well planned. And yeah, I sure would like to have an HD2 to kick around on for a little while.
EDIT: Flashing test build now without the visual edge softening.
