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.
Step 1. Preparations
connect your iDevice to iTunes (cable preferred, WiFi may take forever)

Live Mesh allows accessing documents and files even via web interface. Live Mesh clients are available for Windows XP, Vista and for Mac OS X Leopard. Sadly there is no Linux version yet.
As the Live Mesh technology is still in development the last Mesh update for the Mac showed sad side effects.
The Mac OS version of Live Mesh can be started. Live Mesh seems to be busy for a while but before being allowed to login, Live Mesh eventually crashes. The Live Mesh icon next to the clock is available but the signin option is greyed out. Microsoft has addressed this issue in an article to be found here.
This issue has got nothing to do with if you are running a software hackintosh with EPOS I. nor a hardware hackintosh with EFI-X, this issue is also well known to genuine Macs.
