Well, it's been a long time coming, but people of US are finally getting Samsung Galaxy S II handset. Sprint, T-Mobile and AT&T are all getting in on the Super AMOLED Plus action under the guise of the Epic 4G Touch on Sprint and just plain old Galaxy S II on AT&T and T-Mobile. Verizon is not willing to give Galaxy S II flavors to their customers and we heard they are moving to next Google Phone, Samsung Nexus Prime.
The AT&T version of the Galaxy S II won't have a name of its own. It goes by Samsung Galaxy S II, just like the international version of the smartphone and will basically be carrying the same hardware. The only hardware differences are in the exterior, most notably the controls at the front, where four touch-sensitive keys have replaced the two touch keys and a regular button combo. On the inside you are getting HSPA+ connectivity and the same Exynos chipset as the original Galaxy S II. The Super AMOLED Plus screen stands at the same 4.3", and the TouchWiz-skinned Android 2.3.4 is also a part of the standard equipment.
At this stage we didn't get any details about the AT&T-bound Galaxy S II pricing or availability.
The T-Mobile Galaxy S II will come with a pretty big difference compared to the international version. It will be carrying a 4.52" Super AMOLED Plus, which is no minor difference. In fact the difference from 4.3" to 4.52" is quite noticeable even if you don't put the handsets side by side. The Galaxy S II versions with the smaller screens seem much easier to handle, though.
T-Mobile also remains silent about expected availability or pricing of their Galaxy S II, too.
The Galaxy S II edition for the Sprint network is probably the most interesting of the bunch. Not only does it have a unique name, but it also has WiMax connectivity and the same larger 4.52” Super AMOLED Plus screen as the T-Mobile version. The Samsung Galaxy S II Epic 4G Touch will also feature a larger battery - 1800 mAh vs 1650 mAh for the AT&T and international Galaxy S II varieties. The price you have to pay is a slightly thicker shell, but we didn't find that to make such big difference when we handled the phone.
This will also be the first edition of the Samsung flagship smartphone to actually become available in the states. The Epic 4G Touch will be hitting Sprint stores starting on September 16th for $200 on a contract.
