An FYI regarding warranty service from Otterbox....
My Defender case inner shell was starting to 'squeak' in the lower left hand corner when held because a small gap developed between the two halves of the inner shell. I filled out the warranty claim this morning (this is at about 8AM PST Saturday morning), uploaded a couple of photos of the case and got a reply that I will hear back in 48 hours (business days). Then, 15 minutes later I get another e-mail saying they are FedEx-ing me a new case.
That's what I call service. Kudos to Otterbox.
