I accidentally bought a white iPhone 4 back glass replacement instead of a white housing. Anyone have any clue how to remove the black glass from the back housing?
This is a really, really difficult fix. You can use a craft knife to pick out the glass off the housing. Bear in mind that the glass is very sticky and will be difficult to remove. A suggestion I've hear a couple of times is to use a paint-stripping gun (you know those things with a heated element at the end) to see if that would just lift the glass off. You'll then need to use double sided tape to glue the new glass on.
