Following the U.S. Galaxy S III announcement, AT&T has made the sign up page for the Samsung handset available for those of you interested in getting it. You can now head there and tell Ma Bell that you want to be notified once the phone becomes available in June. We’re really digging the fact that AT&T (thanks Samsung) has left it unchanged, keeping the physical button like the international version. Other than that, the SGH-i747 will have the 1.5GHz S4 dual-core processor, 2GB of RAM, 16GB or 32GB of internal storage, Android 4.0 and more. If you want to be reminded about when the AT&T Galaxy S III launches, head to AT&T and sign up. Are you guys excited?
