Suddenly cydia in my iphone 2g stopped working. When ever i press cydia,it shows loading... and exists out of application. I tried unistalling and installed again, same problem repeated. Is their any simple solution for this kind of problems like backing up whole iphone and restoring when ever things like this happens. i know default restore doesnot work properly. now i need to re unlock and install all my applications i guess !!.. any suggestions ?
