To the poster above the previous one, I don't know why you are worried about the 2.2 update, even if it's just 30% or 20% faster then voodoo, The SGS is still blazing fast when it's working properly. I had the JF4 firmware, I updated using Kies to the JG4 and the phone is flawless now. GPS also works perfect. If android 2.2 just brings some features, i'll be happy enough. (flash 10.1)
