Apple voiding warranties, blacklisting hacked iPhones?

From Engadget -


According to a recent report, an iPhone running third-party apps and operating on T-Mobile was flat out rejected when it entered an Apple store for service. The employee reportedly said that "the warranty was voided," and added that the mobile was "blacklisted" against future service or return. The owner did manage to coerce the Apple store manager to allow a return (albeit with a 10-percent restocking fee added on), but it's highly recommended reverting your iPhone to AT&T mode before returning it for service.
