The Most Common iPhone Passcodes 192
Orome1 writes "The problem of poor passwords is not confined to computer use, and that fact was illustrated by an app developer who has added code to capture user passcodes to one of its applications. 'Because Big Brother's [the app in question] passcode setup screen and lock screen are nearly identical to those of the actual iPhone passcode lock, I figured that the collected information would closely correlate with actual iPhone passcodes,' says Daniel Amitay. It turns out that of the 204,508 recorded passcodes, 15% were one of the most common ten."

Not by default; you can set it up that way.

15% of iPhones are locked using one of ten codes.
You have ten login attempts before the phone wipes itself.
Thus, if you try each of the top ten codes on a random iPhone, you have a 15% chance of entering the right code before it wipes itself.
Also, I think you meant "successive".

App in question in action [youtube.com]. Description from the video :
"This is not a prank application! It really works, and takes pictures of anyone trying to access your iPhone. Big Brother is the only iPhone app which sets off an alarm AND takes a photo if the user presses the home button!
Want to know if someone has been sneaking a peak at your iPhone 4?
Turn on Big Brother, LOCK it, turn off your iPhone, and you're set!
Whenever a person enters an incorrect password, the device will take two photos!"
Not duplicating functionality in the iPhone, not actually stealing your passcode (just its own user settable one is sent back).

is that if someone steals or finds a lost iPhone, he has a 15% chance of unlocking the device and accessing the data within before it gets wiped just by trying out the passwords on the aforementioned top 10 list."
I think that might be off -- If someone steals or finds a lost, working iPhone; he probably has a 80 - 90% chance of finding the device not secured with a passcode to begin with.
If he happened to get so unlucky as to find one of the 20% of iPhones with a passcode; he has a 15% chance of unlocking that locked device.
That brings it closer to a 100% chance of gaining access to it; if the found phone works at all -- only an 85% chance of it using an uncommon passcode. Just because it's uncommon doesn't mean unguessable -- it depends on how much the thief knows or can find out about the person. If the thief gets the wallet too, they might try the birthdate on drivers license or do other research about numbers significant to the person (increasing chances of an unlock beyond 15% for fixed common) -- if we include things like phone numbers, anniversary year, 15% might be a real low ball for the amount of passcodes based on such guessable concepts.
