I have been reading through threads and although its cool that we have this available to us, it seems that after seeing 2.2 in action and reverting back to 2.1. The previous version blows 2.2 out of the water when it comes to speed and bugginess as of now. I guess that is the reason why the OTA update is still not released yet. Has anyone else reverted back to 2.1 and noticed significant differences in overall smoothness or what!?
