If you have mobile terminal you can run
apt-get install cydia
I believe that may work. Or you might be able to find a link to a Cydia deb and use iFile to install it.
If you don't have mobile terminal or iFile you're pretty much screwed and you will need to re-run your jailbreak program on your device.
Thank's Ironman for help but I did't know how to do this, still my phone is working good. Can you help me how can I update My iphone to latest software 5.1.1 (latest). If I update phone, then my local signal reliance should work. Since if I upgrade phone it will be locked and I need to jailbreak for it, to use internet and call.
I did't know much about it, how to do. I need tutorial which tells me how to do this. I am adding one internet tethering snap also
