Extraodinary situation-need help with an iDevice!

[MrHaaax]

And no, this is not a spam, and i have no other better places to put this on.
Lately, i have been trying to hack a few games(this case; Modern Combat 4). Using iFile, i copied the hack into the correct folder, and the hack ended not working(the application exits right away) so i delete it and going to App StoreVn(a cracked game store, because i have a jailbroken iPad 1, iOS 4.3.3) and reinstall it, but then suddenly, most of the apps icon gone missing, and the apps themself crashes instantly. I tried a soft restart, but after that, the apps whose icon missing has gone, including the default apps. Only Chrome still works so i can still post this thing.
I have no idea what to do, i did a Google search on this error but no one has the identical error. I thought of restoring the iPad but it's too risky; what should i do?
And yes, sorry for my bad English.

PS: haven't tried Hard restart. Since i don't have settings so God knows those default apps are restricted and where are the others.
PPS: haven't tried connecting to the computer and check the location of all the crap.

The solution is very simple. It requires only a couple easy steps.

1. Throw the i-device out the window.
2. Buy a Samsung Galaxy Tab II
3. Learn to use a real operating system, not Crapple.
4. DONE!
