Thread about numeric passcode strength on iPhones.
And *this* is why I consider my rooted Android phone to be more secure than iPhones under a whole category of attack scenarios. Because I can use separate 25-character full ASCII *startup* password and an 8-digit *unlock* code.

Guide to iOS estimated passcode cracking times (assumes random decimal passcode + an exploit that breaks SEP throttling):
4 digits: ~13min worst (~6.5avg)
6 digits: ~22.2hrs worst (~11.1avg)
8 digits: ~92.5days worst (~46avg)
10 digits: ~9259days worst (~4629avg)
