According to a leaked silicon gel accessory page for the Samsung Galaxy S II, the highly anticipated phone will at least be landing on AT&T, Verizon, and Sprint in the U.S. The information also reveals the unique names that the phone will receive from each carrier. It will be the Samsung Attain on AT&T, the Samsung Function on Verizon Wireless, and the Samsung Within on Sprint. Oddly, those monikers don’t seem to nearly portray the hardware muscle of the device and we’re surprised to see no mention of T-Mobile. The Galaxy S II sports a dual-core processor, a large Super AMOLED Plus display, an 8-megapixel camera capable of recording HD video, and runs Android 2.3.3 Gingerbread with Samsung’s revamped TouchWiz 4.0 user interface on top. There’s no word when the Galaxy S II will make its U.S. debut, although we wouldn’t be surprised to see a summer launch.
