The cap is not 1 hour ... it is MUCH much longer. At one point I had gotten ahold of my friends phone while he was passed out drunk. He slept pretty much all day, every time the counter ran out, we locked it again. He ended up having to wait 18 hours to finally get to it, since he didn't have his computer with iTunes on it with him.

He'd get text messages/calls and he wouldn't be able to answer them!
