TUAW reports that Consumer Reports still says that even with a free case, the iPhone 4 is a no-go to get a recommendation from the giant consumer testing firm

Consumer Reports believes Apple's offer of free cases is a good first step. However, Apple has indicated that this is not a long-term solution, it has guaranteed the offer only through September 30th, and has not extended it unequivocally to customers who bought cases from third-party vendors. We look forward to a long-term fix from Apple. As things currently stand, the iPhone 4 is still not one of our Recommended models.

Consumer Reports still a 'thumbs down' on iPhone 4
