Only recently have to additionally reported that the jailbreak for the iPhone 4 and iPhone 3 G S even over the internal browser is now possible. As always, the jailbreak only about a vulnerability that closes after Apple as soon as the hackers have released the jailbreak is possible. But this time the security gap is more dramatic, so that even the Federal Agency for security and information technology recommends how you should behave with his iPhone.
Jailbreak on the Web – PDF security vulnerability makes it possible
Usually Web applications can mess up any changes to the file system of the iPhone. However, the hackers who are responsible for the jailbreak, have found a security vulnerability.

Recommends the Federal Agency for security and information technology …
, There are apparently so many potential victims of the security breach that even the Federal Agency a recommendation calls for security and information technology, how concerned should behave, which installed a newer firmware version 3.1.2. All versions with a larger version called up 4 iOS to the latest hit, until Apple closes the security hole with a new version. The recommendation, which we can sign without further ADO, is therefore:
Apple with the next update will close the security gap. Until then, caution is advised with the handling of PDF files well. Remember: If you have installed a jailbreak, this will be no longer available after the update and downgrade to the previous firmware version is usually not or only with great effort.
