Re: Finally. Jailbreak for iOS4.
This method of "jailbreaking" is a bit scary IMO, or it would be if I owned one of these devices. They use an exploit in apple's PDF reader which allows arbitrary code execution. If somebody wanted to they could own your iphone/ipad/ipod/macintosh just by getting you to open a PDF file or visit a website that embeds one.
From there they have access to all of your personal information you have on your phone, e.g. your phone number, email address, your contact's phone numbers, your personal emails, any passwords you have stored on it, etc.
I don't know if any such virus exists in the wild that exploits this in that manner, but it is certain one will show up if apple doesn't patch this hole soon.
