The phone iPhone passcode thing is kind of a joke, unfortunately -- it's fairly easy to extract the encrypted image from a locked phone, then brute force it. Since almost everyone just uses a 4-digit simple PIN, doing an exhaustive search is faster than syncing to iTunes.<p>What I'd really like is TPM-type security built into the phone (and used correctly) to protect from brute forcing a short authentication code, and maybe multi-factor auth. e.g. if the phone is inside my house or office (was on my secured wifi, hasn't moved), there can be less security (longer relock interval, shorter passcode, etc.) than if I am out and about. If there were a way to definitively link my phone to my car, I'd be fine with turning off all passcodes -- maybe due to bluetooth pairing or something.<p>Biometrics might actually make sense in phones, too, although I'm not sure how much I like the facial recognition in ice cream sandwich.
