Dude, that's awesome!
If the HTC One S you're getting is running the Snapdragon S4-version instead of the Snapdragon S3-version, then get that. Or else, get teh S2.
One way to identify the processor type is to check the speed of the processor on the box. If it says 1.5Ghz, then it's the S4. If it says 1.7Ghz, then it's the SGS II. DO NOT get the S3 version of the One S.
