Well, I looked into more. Apparently, you can change it if you remove the digitizer/glass front from the plastic frame. Under the glass sits the home button with its two side pegs that hold it from falling out. Then, you can just slip the whole thing out. There is some double sided adhesive that holds the two prongs to the back of the frame that you have to free up to be able to pull everything out the front.
To do this, you need to buy a new assembly/home button/flex cable, and some new adhesive for your digitizer. You might want to change the digitizer while your at it if its all scratched up.

I would highly recommend looking on ebay, b/c these parts can be found for much cheaper.
Use the iFix it tutorial on replacing the front panel for details on how to get in and out of there.
