Unlocked (what's this?)

What is an "Unlocked" phone?

Many cell phones are designed to use a Subscriber Identity Module (SIM) card to store subscriber data. These SIM cards are issued by the carrier and provide cell service to the phone. "Locked" cell phones will only recognize SIM cards from the carrier that originally provided the phone. Almost every cell phone provided by a US carrier is locked to that carrier’s network.

"Unlocked" cell phones will recognize SIM cards from any carrier using Global System Mobile Communications (GSM) technology. Customers with "unlocked" cell phones are able to use any GSM carrier of their choosing, including "pre-pay" or "no contract" SIM card options. "Unlocked" cell phones also accept international SIM cards that provide discounted rates while traveling abroad.

Samsung SGH-i777 Attain Galaxy S II Smartphone Features

The AT&T Samsung Galaxy S II is the closest to the original global version of the Galaxy S II. Don’t be fooled by its razor thin profile as under the hood the AT&T-bound Galaxy S II comes with a 1.2GHz dual-core Samsung Exynos processor. The chip powers Android Gingerbread skinned with the latest TouchWiz UI, all showing off on a 4.3” Super AMOLED Plus screen.

The best I have had (so far)

This is a great phone, Android platform is well done, the only problem is the synch software provided free by Samsung (Kies). Look elsware, its awfull and does not work most of the time (have a search for problems and you will see).
