Apple has been accused of violation of the Federal Communications Act, three counts of products liability related to negligence, defect in design and breach of implied warranty, intentional and negligent misrepresentation, fraud by concealment, unfair business practices and more. 'The iPhone 4 manifests design and manufacturing defects that were known to Defendants before it was released which were not disclosed to consumers, namely, a connection problem caused by the iPhone 4's antenna configuration that makes it difficult or impossible to maintain a connection to AT&T's network,' the California complaint reads.
