Yeah, and also, if you're looking for cheap, free shipping parts for the future problems, that's ebay.com. I've bought plenty of parts for cheap, and I can bravely say I'm satisfied with them. By the way, I have an iphone 4 and the home button is one of the downsides cuz they brake easily. So as Con said just take the home button from the other one and u should be good!
Also make sure u clean the computer of unnecessary files through disc cleanup and through the "run" option when u press the start button, unless u have windows 8 or other non windows iOSs, I don't know how they operate because I only work with windows xp and windows 7
