In response to complaints about reception problems, Apple CEO Steve Jobs announced Friday the company would offer free bumper cases to customers, according to a wired.com blog.

Customers who have already purchased a bumper case will be offered a full refund.

"We’re not perfect," Jobs said at the press conference held in California Friday afternoon. "We know that. You know that. And [our] phones aren’t perfect either."

Apple has been facing a storm of criticism in light of an antenna design flaw. If held in a certain way, the phone’s two antennas will short out and create reception problems for its users.

The offers will begin next week and end at the end of September, Jobs said.
