Had a early bootrom 3GS, early baseband preserved too. It's the only iPhone that will boot untethered, unlocked and jailbroken on iOS 5. Put a couple local ads up, one with it JB and one with stock iOS 5. I was surprised at getting about 10:1 replies for the stock model vs jb . Anyhow sold it on iOS 5 stock, one less early baseband 3GS in the world Guess JB 3GS phones are not as in demand as they once were.
