I worked for a private company in computer forensics. We had two machines, expensive machines, dedicated to accessing phones. I'm going to go out on a limb here and guess the FBI has something similar, if not better, at their disposal.

Biometrics, also people are horrible at making good passwords/pin codes. There's also normally a few tricks to get around being locked out for X minutes/days/years.
