How can I clear app data? For example, Tweetbot is 10.7mb but in my usage screen it is listed as 634.23mb. I know how to clear the cache in Tweetbot, I just used this app as an example. iTunes reports that I have 6.3mb in apps, but I know for a fact that the size of the apps don't add up to that.
I too have this probelm. I also have about a gigabyte of space which just miscellaneously says other. Ive found that clearing the history and cookies in safari help to clear this up a tiny bit but still looking for help.
