How do I remove the home button and metal + electronic piece from the bezel? I haven't seen anyone cover this before anywhere online. Right now- the bezel is still attached to my old digitizer, but I know to heat it up with a hair dryer to get the glue warm and pry it apart...but as stated...how do I remove the metal piece from the bezel? Just cut those black 'bumps' off? If so...then how will it stay in place on the new bezel ( old one is broken and I've got a new one for it) Thanks for your help!!
