Was dowloading pushdoctor on cydia. It froze. After a long time I went out of cydia by double clicking home button and switching apps. When i went back to cydia it was still on the same screen then I closed cydia and then went back into it said you have a problem which needs to be manually fixed. Then it wouldnt load. I can still use my phone but can I switch it off and on again. WIll there be any problems
