I have a jailbroken ipad 4, currently running IOS 6.1.2. i want to upgrade to the lastest software version, because i want to dl a few apps that are currently incompatible and i think the old software is causing the battery life to be shorter. I know that the only way to really do the upgrade is with itunes, but I am not sure if i try to do so with itunes if it will cause my ipad to brick as it is jailbroken? i am not particularly interested in keeping the jailbreak or having a new one done, i dont use the jailbrak part much. just want to upgrade. will it be something simple to do or do i run the risk of causing my ipad to brick?
