Go to Terminal and try to re-install Cyida. If you don't have Terminal, go to search one and install it into your iPhone.
In the Terminal, type the following commands:
su
alpine (this is password for your iPhone terminal)
apt-get remove cydia (you maybe asked to confirm it, just confirm it, it's fine)
apt-get install cydia
and then re-boot. Hopefully it will work. Good Luck!作者: kncgcg 時間: 2011-4-11 12:15 AM
Cydia recently upgraded to v1.1.1, DO NOT interrupt your iPhone during upgrading in progress, besides Terminal, you may use iFile if you have installed it into your iPhone
