Jailbreakme 2.0 makes use of a PDF vulnerability which is present in iOS Mobile Safari. With the same method, hackers can also make use of this exploit and make user donwload PDF file from Safari. The targeted PDF may contain malicious codes which could have potential of extracting information from your iOS devices. No permanent solution from Apple yet so far but we could expect it to be fixed in the upcoming 4.1 firmware.

Temporary countermeasure would be to install the package call "PDF Loading Warner". It actually warns you whenever there is a PDF file that you are about to download. Just make sure that you only download the PDF which you know is from a safe source. It is more like a pre-warning before you download.

You can get this in Cydia by searching for PDF Loading Warner.
