Re: You can pry my password from my cold, dead lips.
You can set up your iPhone to erase its contents after 10 failed attempts. However, that is intended to protect you from data thieves, not to protect you from the police.
And to protect you from idiot mates erasing your phone for fun, there are time delays so erasing takes over two hours.
But then Settings, General, Reset does the job if your phone is unlocked.
