you don’t want your iPhone to experience is anything bad.

Well now, duh. But let’s take that concept a bit further - what if it was disabled? If you couldn’t use it? If your $400 critical communication device was SOL????

Believe it or not, it could happen. To wit:

… McAfee Avert Labs Blogger Jimmy Shah identified a Denial of Service vulnerability in the iPhone’s Safari browser in a blog post on Wednesday.

“The researchers who found the vulnerability were looking for a method to unlock the filesystem on iPhones with the latest firmware (1.1.3). Unlocking the file system allows the installing of custom ringtones and third party applications. With the last firmware version you could automatically unlock your iPhone by visiting a particular website with the Mobile Safari browser,” Shah wrote.

The DoS vulnerability can be exploited by visiting the proof of concept page and clicking a button that will launch a warning and the exploit code will run. The iPhone is then unresponsive before rebooting a less than a minute later, Shah wrote.

“The DoS bug exploit is partially based on JavaScript code from the Month of Browser Bugs(MOBB). During the MOBB a group of security researchers released an exploit for a web browser vulnerability every single day. While the original exploit was targeted at desktop browsers, the modified version simply attempts to fill memory and crash the phone,”….MORE…..

Scary! Here are some forums that discuss it further:

• Remote iPhone Denial of Service vulnerability exploit attacks 16GB iPhones (and 32GB Apple iPod Touch)
• iPhone denial of service exploit still in new handsets
• DoS attack on iPhone causes memory leak, freeze
