The iPad security breach earlier this month didn't just expose thousands of email addreses, but could also help hackers track down users' physical locations, says a growing chorus of security experts.

A member of Goatse Security had his home searched by the FBI yesterday before going to jail for drugs. The group gave Apple and AT&T headaches over weak iPad customer security; now it's been punished with headaches of its own.

Apple should be angry that AT&T exposed iPad 3G owners' private information to hackers. Layoffs in AT&T's top security office, which reportedly took place just weeks before the debut of the iPad, should make it positively livid.
