Right now, I am posting this from my iPhone 3GS, and iOS 5 runs as good on my 3GS like my dad's iPhone 4. iOS 4 had about 50 mb ram free before, but iOS 5 seems to have about 80 mb free. Do you think iOS 6 should or will be out for the 3GS? The reason why I didn't buy the 4S and got the 3GS is Because I have to be the carrier's customer for at least 1 year to unlock, plus the 3GS has a better feel in my opinion. Jailbroken and Unlocked Too, this phone's awesome!!!
