how many of us use the passcode unlock on our iPhones?

Simple passcodes are four digits long. You can disable simple passcode to require a longer passcode with alphanumeric characters.
You can configure your device to automatically erase all contents (Secure Erase) after ten failed passcode attempts.
MobileMe users can remotely enable or change their passcode using Find My iPhone.
If you enter an incorrect passcode too many times, the device will be disabled temporarily.

Most Common iPhone Passcodes
To kick things off, out of 204,508 recorded passcodes, the top ten most common were:
Top ten iPhone passcodes: [1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212, 1998]
Naturally, 1234 is the most common passcode: mimicking the most common internet passwords. To put this into perspective, these 10 codes represent 15% of all passcodes in use. Most of the top passcodes follow typical formulas, such as four identical digits, moving in a line up/down the pad, repetition. 5683 is the passcode with the least obvious pattern, but it turns out that it is the number representation of LOVE (5683), once again mimicking a very common internet password: “iloveyou.”
Interestingly, 1990-2000 are all in the top 50, and 1980-1989 are all in the top 100. I would interpret this occurrence as a subset of users that set their passcodes to the year of their birth or graduation.
Formulaic passwords are never a good idea, yet 15% of all passcode sets were represented by only 10 different passcodes (out of a possible 10,000). The implication? A thief (or just a prankster) could safely try 10 different passcodes on your iPhone without initiating the data wipe. With a 15% success rate, about 1 in 7 iPhones would easily unlock--even more if the intruder knows the users’ years of birth, relationship status, etc.
