Helllo there and welcome to the forums.
You mean Icarus? No, that is not Android 2.2. Android 2.2 has not been released yet for the U.S. I did install Icarius and there is an overall performance boosts especially when opening apps. There is also a darker theme which helps battery performance. It is just more nicer looking and polished. There is no bloatware, and I really recommend it. Some users are saying that MMS doesn't work, but I have not yet comfirmed it. Wifi does work, and the 3G. I haven't had any problems with it so far.It is definetly worth a try. If you are going to want to install it, I recommend using my instructions as they are more in depth and many users are saying that those are the best instructions they have found.
