You’re running a jailbroken iOS 5.01 on an iPad 2 and you cannot use Firewall iP. Installing Firewall iP shows no indication of errors, but when you try to start it, it just splashes shortly and closes instantly. This behaviour is known to some more applications (like Safari or Mail).
It looks like incompatible iOS Apps are responsible for that behaviour. At the moment there seems to be no known approach to find out which app causes issues, but trial and error.
