It said: "AT&T Free Msg: Your phone is now enabled to dial & roam internationally. Details & rates at att.com/global. See att.com/wirelesstraveltips for iPhone travel tips." Just wondering if anyone else got this message? I haven't talked to AT&T or even logged in online, so seems random. Does this mean anything? Like did my iPhone just get locked, or unlocked, or what? It seems some MR posters got this message much earlier before the 4S was released, but not much was written about it.
