I'm currently on BB v1.0 running at 800MHz.
It appears that Froyo 2.2 has all or most of the functionality of BB 1.0 (except root, of course). It has wifi tethering, significant performance gains (even without overclocking). It also has one huge new feature: Flash 10.1.
I'm debating about what to do, and am hoping to start a discussion along the pros and cons of going back to stock for the Froyo upgrade.
Since most of the reason I have root is to get the features which Froyo has without root, is there a reason I should stay on BB? I will probably go back as soon as a BB for 2.2 is out, but until then, are there features in BB that I'm missing that would change my mind?
