Hope this isn't too dated...I have seen some comments for this rom and DERP regarding DT's A2SD. It took me a couple of times to realize this but I believe that the APPs2SD versiion cooked into this rom is the CM version??? Anyway, don't flash DT betas or try and use A2SD GUI because they don't help. I have EXT3 and been using DT for over a year with no issues. If I just leave the rom alone, it seems to move apps just fine and leave me with about 70MB free on this rom and 100MB on DERP.
