It is unquestionably the home button itself...it's a known issue, and one that the Apple store knows about too. I got my iP4 replaced (and it had water damage too, lol), they asked what was wrong, i told them the home button wasnt responsive at times and the proximity sensor was also still having trouble...no questions asked, got a new handset.
Mine has homebutton problem too that my wife's doesn't have. I'll probably exchange it when untethered jb comes out.
