Hi guys Since a few weeks, I've encountered some problems with my iPhone. * The earpiece doesn't work anymore: It's probably damaged, because the loudspeaker still works. What do I have to replace? * Weak 'Location' signal: When I try to find out where I am on the map, the dot will end up a few miles further and after a few seconds it will come closer to the actual location. Since it works so bad, my Tom Tom navigation always displays 'weak signal'. What can I do about this?
