Apple announced at their press conference today that they will be giving every single iPhone 4 user the option to get a free case to help the antenna issue. Apple has said that they cannot make enough bumper cases for everyone, so they'll pick a few cases and you'll be able to choose which one you would like to get free. If you have already purchased a bumper case from Apple, you'll get a full refund for it.

To apply for a free case, visit Apple's website starting late next week.

This offer is available for every iPhone 4 user until September 30th, 2010. Also according to the Q&A session that followed the conference, this offer will be extended outside of the United States as well, possibly after September 30th.
