Regarding (2): Did it existed before Galaxy SII have been launched or prior to Galaxy SII's conception?

Well, obviously I can't say for certain, because I don't have inside information about how long the design of the GS2 took, but given that the GS was new when these images were first making their rounds, I'd suspect they're from before the GS2's conception.

And, given that I posted this in response to your earlier post which seemed to be claiming that these *fan-created* images were evidence that Apple was copying the Galaxy SII, I'm not entirely sure what bearing the age of a design which had not yet been publicly released at the time has to do with the discussion, other than to provide the answer of:

"No, I couldn't possibly have copied your design. I'd never seen it because it hadn't been released yet. Besides, the drawings you are accusing weren't made by us, they were made by our fans, based on *our* publicly released designs at the time and a bunch of unconfirmed rumors about what our next product would look like."
