PSA: For those who have iPhones and want to crack, hack, or jailbreak them. One of the most popular tools for doing so is a .pdf document you simply browse to online. It takes advantage of a vulnerability in the iPhone’s operating system security to unlock the phone(basically, a vulnerability in the iPhone’s buffer overflow). So, if you *trust* the hacker who wrote that application to have only put in code to break the ties to AT&T and nothing else, then feel free to do so. But as I work for a software security firm, and we specialize in protecting our customers from releasing software with such vulnerabilities, and after watching people there shudder when this “fix” was brought up in conversation, I’d strongly advise against it.

If you want a smart phone without AT&T, get an Android. If you want an iPhone, stick with AT&T…unless you don’t store any personal information on the phone…then you’re probably perfectly safe.
