Yesterday, JailbreakME was released to jailbreak all iOS devices including iPhone 4 Apple device, but some people asked “if comex could figure out to access our devices through a website! then why can’t anyone get in there?” Well, that’s true, it really opened a security hole and it allows for malicious access for your device.
Comex used an exploit involving PDF files in your device so it can install Cydia, but it can install any other files too! Well, our advice is not to open any sites, not to open any links on your Mobile Safari browsers. Just stay away from hackers.. Also, there’s a method to fix The PDF Exploit after jailbreaking with JailbreakMe found it on BGR, you can try this steps on your own risk:
