And the reason I'm not "Googling" is because not a lot of the websites are completely "Up to date" with downgrading, and this, and that, and the next thing-- And just for the fact I seem to get straight answers. What are the complete risks? Can I still use 3.1.3 firmware, Whited00r specifically. Can my carrier "Sense" anything different? (They're real picky and I don't need some email asking for an Ipad plan..) Can you downgrade back to a lower baseband?
