It takes so much heat that it is concerning that damage might be caused to the internal parts. It is difficult to heat the glue, pull the case apart and insert the pick at same time. May need some more pointers to handle these situations first, to prevent possible damage. Also what about the glue that is heated and then cooled before opening? Does it run inside and cause greater adhesion after it cools? Another thing, the handling may cause the phone to turn back on while working to separate. Don't know that that is of concern.
