Doesn't rooting stop you from getting ota updates like ics?
Not necessarily. What people did for the last OTA was relock and RUU back to the stock state then accept the OTA. I'm already on the ICS leak and would be hard pressed to take the OTA anyway. In my 3 years on Android I've only accepted one OTA. That was the first one on my OG Droid and I'll never do it again. I'll wait for a ROM dev to cook the OTA into a ROM or I'll just sit on my existing ROM forever before I ever accept anything from Verizon again. What I'm getting at is that most of the OTA's are horribly buggy and seem as if they've never been tested.
