Okay man I ain't trying to argue with you I'm just saying if he is having problems with the .181 update he will still have the same problems with ICS and most likely will not be solved unless he wipes. Especially since he is going from GB to ICS. It's really just good etiquette to wipe. Sure some people have no problems but most people do. Same is true for changing roms.
+1, never hurts to wipe. Always a good precautionary measure especially when going from GB to ICS.
