> it's really unsettling to think that a simple website could remotely exploit a security flaw and provide complete access to my iOS device.
The thing is, these exploits exist before the jailbreaks themselves. If jailbreaks were no longer released publicly, the exploits would still be there. Who knows what would have happened if they were discovered by someone else (and who knows that they actually weren't)?
When the PDF exploit was found for the last jailbreakme exploit, the first iOS users to have a patch available to them were those who jailbroke their devices. Apple followed shortly thereafter.
Jailbrake is good, I jailbroken my 3G after one hour outside its box. (And I used your VNC implementation to allow a disabled friend in a wheelchair to use an iPhone)
That's said, exploiting a hole in the pdf renderer is scary. This shouldn't be possible.
