We just saw a great product at the TC Disrupt Hack Day. It’s basically a class action lawsuit generator against AT&T that uses your actual call drop data to tabulate how many times your phone crashed and how many times you’ve been generally hosed by AT&T.
The site is worstphoneever.com and it searches for baseband crashes on your desktop, uploads them, and saves them to a database. The results are tabulated and added to the total, eventually leading to a detailed class-action lawsuit.
