Apple announced a remedy to the iPhone 4 antenna debacle today at an iPhone 4 press conference. Everyone who orders or has already ordered an iPhone 4 can get a free iPhone 4 bumper until September 30. Anyone that has bought a bumper before the announcement can receive a refund. If you don't like the iPhone 4 you can get a full refund within 30 days of purchase.
AppleCare figures show complaints about the antenna problem are at 0.55 percent of iPhone users. Although large amounts of iPhone 4 owners might not be complaining, Apple obviously doesn't like the negative press. Unfortunately, Apple can't make enough bumpers for every iPhone 4 so Apple will find some other cases that also remedy the problem and give users a choice to pick which one they want. iPhone 4 owners will be able to apply for a free case late next week.
If you have been following Consumer Reports non-recommendation of the iPhone 4, this announcement hasn't changed anything.
