Title says it all. How can one exchange a clearly defective phone if Apple tells its store employees to refuse anyone with antenna issues? I'm sure their response would be "buy a bumper". That doesn't help me. Is the return/72 hour hold/new phone method the only option? Also, is it more or less confirmed that the most recent phones are "fixed"? I've heard that people who got exchanges received perfect phones with no issues. Anyone with that experience? Thanks!
