Okay let me help for those that are having issues with facetime and mms. Just go to Cydia and wait for the load to finish and see the home-cydia screen, then press the reload button on the top right and after it loads for the second time is complete, go to settings/phone tab and you will see the facetime on and off buttom. On the mms just go to settings and scroll down until you see messages and make sure you see the on and off buttom. That's how I did it without restoring my phone. Good luck
