The newly released iOS 5 beta 4 brings the Over-The-Air (OTA) iOS firmware updates for iPhone, iPad and iPod touch. Actually, if you are using iOS 5 beta 3, then, you can easily download and install iOS 5 beta 4 OTA without connecting to iTunes. But, if you have jailbroken your iOS device, then, you won’t be able to update the iOS over-the-air.
Well, Musclenerd, the active vocal member of iPhone Dev Team, has confirmed on Twitter that iOS OTA updates won’t work on the jailbroken iPhone, iPad or iPod touch due to an explicit check of /Applications. Actually, Apple’s OTA iOS update software checks the /Applications folder to see if it’s a real directory. Also, the jailbroken iOS device users can update to the recent iOS through iTunes Sync.
This isn’t Cupertino company’s first attempt to prevent iOS 5 jailbreaking. Also, it has been reported about the blob monster that Apple has in place in iOS 5 to stop users from downgrading firmware using SHSH blobs.
