Why doesn't Apple just give away free bumpers to those people who are experiencing signal issues due to the capacitive coupling and when customers come in to receive their bumper, they can schedule an appointment to get their phone replaced at a later date?
Problem solved.
I think that would be the perfect solution and that would make me happy. It would show they took it seriously and were willing to make it right. Then for the effort I would have a bumper for my new phone.
