Back to the old days of, “Don’t open the email you don’t trust”, actually, that still applies today, but now, it’s with an iPad or iPhone rather than with a Computer. One of the cons not to Jailbreak is the quote from Mashable Apple below, but so much pros I can’t live without, such as the DisplayOut program in Cydia, that gives the ability to Mirror your iPad exactly as your eyes sees it to a projector or screen. And the Wi-Fi Sync in Cydia, ability to sync via iTunes without being tethered with a cable. Until IOS 4 comes out for the iPad, I’ll be using Backgrounder from Cydia to multitask. Read on below from Mashable Apple.
Quoted from Mashable Apple:
“By just loading a PDF file on your iPhone, iPad or iPod Touch, you could be handing over complete access to your device in what could quickly become a major security breach.
The same technique used in the first web-based Jailbreak for iPhone can be utilized by hackers to seize control of your phone via a program that can be delivered via PDF to any iOS device running 3.1.2 or higher, according Gizmodo and CNET.
Here’s how it works: whenever a user loads a PDF document, it has to load the fonts associated with it. A font can be inserted into the PDF containing a program that will cause a stack overflow. The result is that the program can pass the iPhone’s security defenses and then break out of its protective sandbox to deal critical damage to your phone.
This exploit is how JailbreakMe is able to jailbreak the iPhone just by visiting the website and sliding the “Slide to Jailbreak” button. While JailbreakMe may be benign, hackers could reverse-engineer JailbreakMe’s exploit for their own nefarious purposes.
Because this exploit can be launched just by clicking a link, it could quickly become very dangerous if Apple doesn’t release a new version of iOS with the fix soon. For now, check the links you open and don’t open PDFs unless they’re from sources you completely trust.”
So if you have the iPhone 4 or iPhone with IOS 4, or an iPad and you would like to Jailbreak it with the latest from Jailbreakme.com, either wait or live on the edge. I live on the edge, so I Jailbroke all my iDevices. It’s not like I’ll be opening PDF’s just for giggles.
