I have moved over all the apps to SD that I can (using Apps2SD Pro). The ones that are left are 21 apps taking up about 50 mb. I only have about 37 mb free. What is taking up the other 175 or so mb? I am tired of running out of space, so is there any of that I can get rid of? I have cleared the cache as well, but that only makes up about 3 or 4 mb each time I clear.
