We have already told you about an upcoming tool named Antid0te which promises to enhance the security mechanism of all the current jailbroken iOS devices so that they are secured as much, or even more than the non-jailbroken iOS devices. This new method uses ASLR (Address Space Layout Randomization) process which has been absent from all the current iOS devices, making them vulnerable to attacks such as the ones demonstrated at Pwn2Own contest.
In a TED talk held last month, Cydia creator Saurik said that only about 10% percent of iPhone users jailbreak their iPhones. One of the biggest reason why people don’t jailbreak their iPhones is because of the increased security concerns, which may effect their private and confidential data stored on the device.
