I have an iPhone 6 (64GB), on 8.1 jailbroken. I currently have 33.7 GB of "Other" in the iPhone storage. I have deleted caches, cookies, dowloaded and ran iCleaner with no effect. Last night i went to bed with ~5gb of free memory and woke up today with zero bites available. The only thing that I can think of that may be doing this is something is going wrong when my phone backs up to iCloud. (I have tried many of the things on this list http://www.reddit.com/r/jailbreak/comments/1ez4f7/psa_the_guide_to_cleaning_up_your_other_section/ ) with nothing working. Anyone have any ideas here?
