Install 2.0.6 from cydia ( latest ) . i (f2D) installed using 2.0.6.2 from bigbossrepo and it worked like a charm, no problems at all
this is what i did step by step

i had the crack version so i uninstalled it.
i installed version 2.0.6.2 from teh big boss repo
i did not open it
i placed all the files form the crack where they belong including pwnplayer(musictest.app)
i set permission 777 to ALL FILE AND FOLDERS
i resprung
i it ok like a charm and even saved my old sms from the previous version.


SSH every file to the corresponding directory , apply 777 permissions to iRealSMS_ and 777 to iRealSMS.dylib.
again , iRealSMS_ goes to /Applications/iRealSMS and iRealSMS.dylib goes to /Library/MobileSubstrate/dynamiclibraries

IF this doesnt work for you , uninstall irealsms , go to cydia again , install irealsms , and on the restart springboard screen , ssh into your phone - replace the files and then press tap restart springboard on your iphone .
