The Galaxy S II was officially announced for all three major US carriers. Sprint would be first, with availability on September 16th at $199. AT&T and T-Mobile had their own versions coming but neither carrier committed to a date or price at the time of announcement.
All three variants shared core hardware: Super AMOLED Plus displays, dual-core processors, 8-megapixel rear cameras with 1080p HD video, 2-megapixel front-facing cameras, 4G network support, 16GB onboard storage with microSD expansion, and Android 2.3 Gingerbread. Each carrier’s version carried its own unique software content and branding.
The Galaxy S II had already sold 5 million units internationally in 85 days before its US launch, making it Samsung’s fastest-selling smartphone at the time.
