Apple's iPhone 4 Antenna Issue: Free Bumper case and Refund option
Eligible to receive the free bumbers are the 3 million people who already bought the unit and new buyers through Sept. 30. If you already bought the bumper cases, a refund will be given to you.
If users are still unsatisfied, they can return the phone for a full refund.
Apple CEO Steve Jobs, "And if you're not happy, you can bring the phone back. We'll give you a full refund within 30 days. No restocking fee. We want to make everyone happy, and if we can't make you happy we'll give you a full refund."
The reception issue became a major scar and an embarrassment to the company but still it is a major leap in terms of specs and sales. Improvement will be surely be taken in the next batch of iPhone 4.
