They are giving everyone a case for their phone, which helps alleviate the exposed antenna issue. They also went a long way towards showing that most, if not all phones suffer from something similar and that they have the resources to test their own phones in-house better than consumer reports. They also admitted that the reason the 4 may suffer from more obvious antenna issues is that it's obvious where to hold the phone if you want to attenuate the signal. All in all I'd say it was about the best you could expect out of a large corporate entity. The case solution will probably cost them ~$100M in combined costs and loss of revenue.
