As you can see in the photo above, the two phones bear a striking resemblance; unlike the international version, the Attain will retain a search key and forego the use of a physical home button. We recently wrote about the popularity of the 3 button layout, but speculated that like the original Galaxy S, the U.S. versions will feature the 4 capacitive button layout. Aside from the .2 inch difference in screen size, you will notice that the power button is chrome, and the sides are jet black rather than gunmetal.
The dock is also a pretty nice piece of kit: it lets you charge your phone while allowing you to view your phone in portrait or landscape and it also features volume control, and HDMI + 3.5mm jacks. The dock is currently priced at around $75.99, and can be found along with a slew of other accessories in a previous article.
Rumored for release late in Q3, the Galaxy S II is the de facto king of smartphones, and when it comes to AT&T as the Attain, it will also come packed with a 4.3″ super AMOLED plus display, voice commands, NFC, 8MP full HD camera/Camcoder, 2MP front camera, and of course 1.2Ghz Dual core processor and Android 2.3 Gingerbread.
