Looks like it's time for yet another episode of When Apple Fights Back. As a step in the fight against jailbroken iPhones, it appears that Apple's iTunes 9.1 update disables iTunes syncing with jailbroken units.
According to MobileCrunch, issues are also surfacing with "'tethered' jailbreaks," which refers to jailbroken iPhones that have to be connected to the computer each time the device is powered on. Reports are scattered, with some claiming to have issues, and others experiencing no sync issues whatsoever. What's more, iPhone hacker ih8snow claims that the blackra1n issues are limited to Windows - in other words, those using OS X to sync their iPhones shouldn't be having issues.
With all of that said, I turn the floor over to you. Did the update keep your iPhone syncing intact? Are you having issues? Sound off below!
