Protect yourself from iOS4 security issue

Some of you might have heard about the security breach in iPhone 4's Safari.

Basically this happens only when you visit a malicious site and open a PDF file.  This compromised PDF file can contain some special code in the font and create something called a stack overflow.  This code can gain access to the phone and control the device. 

Apple has already fixed this problem and an OS update will be coming soon. 

Here's what you can do in the meantime to protect yourself from this:

1. Don't visit sites you do not trust;
2. Alternatively, use Opera Mini for the iPhone in iTunes, as there aren't any reports on that yet;
3. For those who like jailbreaking, that's also an option.
