I'm actually pretty surprised that you're stock and want to go back to Froyo. Maybe you just had a better phone than I did. If you've run into any of my posts since I got my phone in Aug 2011 I've had nothing but nightmares and a very unstable working phone. Finally when GB came out it has fixed about 99% of the problems I've had and now I feel like I have a brand new stable phone that also boots up much faster, runs faster and is very stable. I can live with the camera sound but I couldn't live with all the things that was wrong with my phone before getting GB. Now I love my phone. The only thing I wish I had was more internal memory since apps are getting bigger. 512 just isn't enough now days, it should be at least 1mg of internal memory on phones now days.
