I JB my 4S a couple of weeks ago and have been very happy with the results but in the course of personalizing the icons and dock a couple of strange things happen. 1. when I change my theme, the settings icon goes away 2. when I work with the dock, the phone icon goes away 3. when my phone icon came back, it's just a big, white squarish blob. I can get these both back if I go back to the original theme I did after JB. Is there any way to solve this other than to restore the phone to the Apple iOS and then re-JB? Has anyone else ever had this happen?
