A leaked press snippet appears to confirm that the Samsung Galaxy S II will appear on T-Mobile, AT&T and Sprint, with Verizon conspicuously absent. We had previously reported on the fact that an event to be held Monday, August 29th was the likely date for Samsung to announce that the phone is coming to the US market.

The shot shows the fairly standard Galaxy S II that we’re used to on AT&T, but appears to indicate a variant model on T-Mobile and what seems to be a different flavor yet on Sprint, although it’s difficult to tell from the image. Although it is likely that the Galaxy S II will be announced on Monday, Tmonews is reporting that at least the T-Mobile variant might not show up until October.

The Galaxy S II has been a watershed success for Samsung, selling over 1 million units in Korea by May and 5 million units worldwide in June, even before hitting the large US market. It has proven to be the closest single-device competitor to the iPhone 4, which sold some 20.3 million units in the last quarter alone.

The Galaxy S II, with its 4.3″ Super AMOLED screen, SPA+ 21Mbps/ HSUPA 5.76Mbps radio, Samsung Dual Core Application Processor and 8MP rear camera with auto-focus and Android OS 2.3 Gingerbread should do well as a flagship Android device here in the US.
