Watch out! The earphone speaker is glued with tape to the back of the screen. If you try and remove it with tweezers it will disintegrate. Better to leave it on, then slice it off with a razor blade once the screen is off.

Also, if you do need to keep your frame (and remove as per the hot air trick in the previous comments), be careful that the screen is flush in the repaired item - if it protrudes at all it will break again next time you drop the phone. I ended using a few dabs of superglue (applied from the outside after re-assembly) as my double-sided tape didn't really do the job. Also if the screen is not quite flush by the earphone speaker, the speaker contacts will not make good electrical connection as they reply on pressure from the screen to hold them against their contacts.
