The only good news is that Apple will offer free Bumpers for everybody who own an iPhone 4 (what an incredible fix, Apple!), and when they will run out of Bumpers, another accessory for your device will be offered. But this happens as long as you bought your phone before September 30th. They also claim that they spent over $100 million in special rooms, where they tested iPhone's antenna, and they didn't discover any problem.
Moreover, they also said that only 0.55% of iPhone 4 owners called AppleCare to complain about the reception issues. If anybody finds details about this problem on the internet, who they think that is going to call them just to be told that the phone doesn't have any problem with antenna?!
Personally, I am completely disappointed by this policy of Apple. Are they ever going to admit (maybe in the following 50 years) that the iPhone 4 had problems with antenna?
