Job done….With a smashed screen remember to apply clear scotch tape to hold the screen together. Continue to heat the remaining stuck shards when the main bulk of the glass comes out. Pick them out carefully, and not to raise the gasket. Use a strong magnifying glass. the ifixit heat gel pack and tweezers helped me. Ensure that all tiny bits of glass have been removed form the body. Just turn it upside down, give a couple of gentle taps with something plastic. Pick out if necessary, taking care around the components. For a smashed screen, needs a good hour or more.
