I have a jailbroken iPhone, and it's low on space. Much of the wasted space seems to have been consumed by the "Other" part of the space display in iTunes.
How can I get a breakdown of how that space is being used? The restore process from my backup may have left some extra crap around, so I'm thinking that maybe some of it's just incidental data that I could clean up if I knew what was there.
On my mac, I'd use DaisyDisk or something like it; does something like that exist for iPhones?
