How would you like your Samsung Galaxy S II with a physical QWERTY keyboard?

That's the option that will greet AT&T customers in the US, where pics of the physical-keyboard packing handset have been leaked.

Although widely available in Europe and Asia, Statesiders are still waiting for an official launch of Samsung's flagship smartphone - with carriers putting the finishing touches to their variations of the device with August release dates expected.

Like the original Galaxy S handset, US carriers will be giving the handset individual names - Sprint will offer the Samsung Within and Verizon's is called the Function.

The AT&T Attain variation (model number SGH-I927), pictured here, is the first time we've seen the S II with a QWERTY option. The Android 2.3 handset looks just the same as the original bar the keyboard - although a bit fatter and with a textured back cover.

Samsung recently announced that it had sold a whopping 3 million Galaxy S II handsets in its first 55 days. With the US launch still to come, it's fair to say that this is Samsung's most successful Android smartphone launch yet.
