There is, however it's tethered. What that means is, if you have to reboot your phone, you will have limited functionality until you jack back into your computer and boot it out of that mode. Some people absolutely hate this. I don't mind it, you just have to use some common sense and not download cydia packages that require a reboot while you are out and about.Isn't there a iOS5 jailbreak? What would be the difference? Pros/cons?
