Apple just announced in the Apple iPhone 4 Antenna press conference that all iPhone 4 owners will get a free bumper and refund if they have already bought one. From September 30, each iPhone 4 owner will get a free bumper. iPhone 4 owners can choose which case to get from the website starting late next week. iPhone bumpers are cases designed for iPhone 4 by Apple.

Earlier, Apple said that only 0.5% people called Applecare to report iPhone 4 reception issue.
