The fact that it hasn't shown up in the FCC doesn't really mean much. It could mean that they asked the file to be private till a specific date. Really, the fact that we haven't seen it at the FCC kinda makes you wonder that it will have LTE, which could be the reasoning for it being private. Also, rumors point the Bionic to launch early September. So if the Galaxy S II isn't here by the 12th, that means a) it won't have LTE and is coming late August or b) it could launch mid to late September after the Bionic and right before the iPhone 5. Really though August 11th is a solid date to consider when you look at what's coming very soon.
