Several iOS versions ago I used Pangu to jailbreak my phone. Now that tethering is included in most unlimited plans I no longer need to be jailbroken. I've tried to completely reset my phone, even put it into DFU mode and do a clean wipe of the operating system, but my issue is every time I restore from iCloud somehow it gets some of the jailbreak files back. Mainly this prevents me from updating my phone OTA, which is an annoyance to me.. Is there anyway that I can completely remove this jailbreak Without having to discard my iCloud backup? I have over 100GB of stuff I really don't want to loose.
