Hello I recently downloaded a cydia tweak for my IOS device(SB rotator) After downloading and installing the tweak I rebooted to find that it would stay on the reboot logo. I have tried powering off the device and rebooting and the same screen comes on. What can I do to stop this screen from coming on so I can remove it in cydia. Any help would be muchly appreciated. Running IOS 5.0.1 and it was SB rotator 2.1.5. I have now figured that the firmware required for this tweak is 3.4 to 4.1.
