I ran this on my iphone so I could install tetherme and it worked fine. Some while later i had to reboot my system and I lost tetherme and Cydia so I ran the redsnow JB again. It asked me to run it in DFU mode so I did with no issues and all seems back to normal. If I have to reboot my phone and lose tetherme and Cydia again, do I need to run the JB app again to re-install these features or can I just reboot the phone in DFU mode like described in the JB install to get tetherme and cydia back? I hope this makes sense, new to all this. thanks for any help.
