iOS users should refrain from downloading PDFs says Apple

Remember the potential security theat in iOS that Apple was reported to be fixing last week? Well, the fix still isn’t here yet – at least not officially. It turns out that jailbreaking your iPhone is the key to solving this problem. Gizmodo suggests that users use JailbreakMe.com to jailbreak their devices and then download the PDF Patch to patch the hole. Once that’s done, they can choose to un-jailbreak their devices if they wish.

For the not-so-daring, Apple has recommended that users stay away from PDF files for the time being – meaning don’t open them on your iOS device but if you really have to, make sure they’re from a trusted source. Or you can stick to viewing on your computer instead. Stay tuned and we’ll keep you posted when Apple releases the official PDF fix for iOS.

iOS was once upon a time called iPhone OS, or "operating system", which is the software that provides all the basic device functionality and is the interface between the hardware and applications. iOS was introduced with the iPhone on January 9 2007, and it was originally not intended to be programmable by third parties. Steve Jobs had envisioned that developers could create Web Apps that would run in the browser. This changed less than one year after when the iPhone SDK (software development kit) was introduced in October 2007. Today, hundreds of thousands of apps have been created for this platform. iPhone OS became iOS on June 2010. Interestingly, both iPhone and iOS were former trademarks of Cisco, that Apple now uses under a license.
