After doing the Evasi0n jailbreak I find my marvel war of heroes won't load?

Anyone have any info on this, I found my friends jailbroken iphone also does this, but his kids jailbroken ipod is fine… Any suggestions, might get rid of the jailbreak and restore the phone if I can't fix this, kind of addicted to the game haha

Yes, but you must follow this tutorial: http://wp.me/P38aqZ-6P Pay attention!

1. Uninstall all the themes you've installed from cydia.
2. Then uninstall winterboard from cydia.
This should work.

If that doesn't work enter your iPhone into "safe mode". The game should work now.
