Recently, Apple released an iOS 4.3.4 update to patch a PDF vulnerability that allowed several pirate crews to jailbreak the iPad, iPod and iPhones. The effects on piracy advocates such as Apptrackr was negligible however, with an iOS tethered jailbreak being released by Redmond Pie, a short time after Apple’s update.
This jailbreak enables access into Cydia for all current iOS devices, save for the iPad 2. However, due to the nature of the jailbreak, some users have advised potential pirates to wait for an untethered jailbreak, to prevent the inconvenience of re-jailbreaking one’s phone after every update.
Current users of jailbroken iPhones don’t have much to miss out on though, considering that the only updates in the latest iOS are there to prevent the jailbreaking of iOS devices, except perhaps, the ability to delete and cancel downloading applications.
