A U.S. man prosecuted for exposing a weakness in how AT&T handled the personal data of its iPad users filed an appeal on Monday of his conviction and 41-month sentence. Andrew Auernheimer, known as "weev," created an automated tool to extract the names and email addresses of 114,000 iPad 3G owners from AT&T's servers, which were used by customers to access their accounts. The information was later passed to the online news site Gawker.
