So I have downloaded a few JB apps and such but I want to make sure I maintain a good amount of space as I have the 16GB 3G Ipad 2, so i can only upload about 2 movies on it . I dont have any music on it as I have my phone and ipod for that, but are there any files or anything I should get rid of in iFile, or anything I can do to get the most space out of my ipad 2?
