Description

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.

This device is also known as Samsung SGH-i777, Samsung Attain

I got this phone on black friday and absolutely love it! I looked at the Skyrocket too but i could tell a difference between this phone and the skyrocket and that the better processor was in this one. I have add a custom rom onto it and love how customizable it is. I am really pleased with the SII it is leaps and bounds better than the Captivate and i loved the captivate but this phone is just a goliath and has truly been a joy using and having. I have never had problems with the reception.

AT&T Samsung GS2 and AT&T Samsung GS2 Skyrocket
I currently have both of these devices of course Exynos chip set just little bit on the faster side when you flicking screens side to side if you have the devices sitting next to each other other that there is no lag at all it a very fast responsive device at&t GS2 has smaller screen skyrocket is bigger when it comes to graphics display size matter chipset,cpu and gpu all must work harder due to skayrocket screen is 4.52" vs at&t GS2 4.3"
