Hi, I have pwnd a first gen US iphone sucessfully and I get Voice calls fine with my Vodafone network SIM. I do have an issue with data though - I get "Could not activate cellular data network: You are not subscribed to a cellular data service". I have contacted Vodafone and they say everything is fine with my unlimited data plan their end. They think it may be an issue with the Phone. I told them it was an HTC I was using . But they think it should work. On the iphone I have gone through: Settings -> General -> Reset -> Reset Network Settings. and restarted by that has not fixed it. Any ideas???? Sooo close.
