[TIP] How to make Opera Mobile 10 the default browser
After spending several hours messing around with the /Windows/OperaL.exe file to no avail, I finally figured out how to make the new Opera Mobile 10 the default browser, so that bookmarks launched from Manila's Internet tab will open there and not in Opera 9.x. It's actually very easy.
First, copy the entire contents of the /Program Files/Opera Mobile 10 folder into the /Windows folder. It's important to copy more than just the .exe file, otherwise the program won't launch.
Next, use a registry editor to change
Finally, soft reset and you should be all set. There are probably other ways of doing this; please share any other methods you may know.
Update: this method doesn't seem to be working for everyone; suggest you read the entire thread, as Dsixda has kindly posted a CAB which makes multiple registry changes. Also, see posts #2 and 3 for an alternate method that has worked for some.
