Honestly if i never found out about CB my BB wouldn't be what it is today. The CB launcher should be pushed with the service books and instead of running setup wizard it should make you read the 101 forums.
If i downloaded the curve 8900 os from torrentz, could i load it into my 8330?
why would you download an OS from some ghetto torrent website when you could just get it here? and if you want your 8330 to look like the 4.6OS, you can download the theme that does that for you.
You cant load an 8900 OS onto a curve, it wont work.. get your OS from whereever you want, but you will need to download one for your 8330 (at your own risk)
you cannot load another OS for your BB if it is not the right type. Besides I had a friend that loaded an OS from a torrent and she ended up getting a virus and the whole BB crashed. She had to get a brand new one...
