I have EvilEris 3.0 ROM and of course I have a2sd. I have been reading alot of good things about XTR and thought I give that a spin, however, I have a couple concerns: 1. How will things react when I switch (in regards to a2sd) 2. Will I need to go through the process after I partitioned the SD all over again with the new ROM 3. Will I be able to revert back to my nand backup of EE with all the a2sd stuff intact if for some reason I decide to go back?
