I went into the registry and found that the values were already set to have Opera 10 as the default.

I again tried to edit the xml file and I still get the

The file cannot be opened. Either it is not signed with a trusted certificate ... etc

I was able to go into the "File Explorer" and manually click on the Opera10-armv4i.exe and Opera 10 will start without a problem.

I am not sure what is happening with the "Internet tab" that is causing the error.

I am running a "leaked version of 6.5 for t-mobile" but I am going to try an install the official version signed and released by t-mobile to see if that makes the difference.
