So i had this exact same problem after checking SkyFire as my default browser and decided it wasn't the best for everything i do, I then had ALL of my email links and other sources opening in PIE. i spent hours (about 3) searching, to no avail, i gave up and set SkyFire as the default again.. somewhere in between then and the next day, Opera had become the default browser for everything on its own.

btw. The Sprint Music Store opens up on Opera on my phone.

Summary : No Reg Edits (even though i was looking for them) no trickery in the settings or anything, Opera became default by ... default
