iPhone No App store,camera or cydia apps after Pangu 1.1 jailbreak

Are you sure you didn't:
1)update OTA
2)set date back to June 2nd
3)disabled passcode

If you did everything there then I would do a clean restore and update to 7.1.2 and try again. Possibly the Pangu download is broken...did you download from their site or a mirror?

I also have a 4 and it works perfectly...

When I JB my sons 5s, a few icons disappeared. They came back after I installed something from cystic again and rebooted. Hope this helps.
