I saw on Xda you can get all the original stuff back by copying all the .dat files from the original Q folder in the imarche thingy lol. and putting them back in the spb mobile shell program file and overwrite. Only problem I had was once I did that I would get errors after deleting the new skins thing from my storage, so I did a MS3 reinstall right over exsisting one and everything was saved except my backround. All widgets were in place.
