It's probably crashing because you've installed appsync(and god knows what else). It doesn't work correctly on iOS 7(or 6 for that matter) and not only that but it permanently modifies the files so you can't fix them without a restore.

Also used for piracy which we don't support.

I don't support piracy either, but to say the OP "probably" installed appsync is irritating. I had the same problem without installing appsync or any other pirate program, and my JB had similar issues with only 2 Cydia tweaks installed, both ios7 compatible and both paid. The fix described by a previous poster worked for me, but OP may have a different device/iOS than me. The post @naraj811 posted (to give credit) was: "FIX: delete app sync if you have ... install ifile ... go to Var>mobile>library>caches .. delete a) "" (your numbers may be different, I'm not sure, but just find the similarly named file. There's only 1 like it) b) "" reboot your device ... after rebooting wait 1 to 2 minute to device become normal ." iPhone 4 CDMA 7.0.4

In my defence almost 90% of people with this issue here admit to installing appsync so it's not that far fetched to assume it in this case. Especially since they mention it in the question.

If you have this issue and you've never installed appsync, make a new question and clearly state this so we can help you better.
