How to fix some mysterious problems.

I jailbroke my iPhone 4 4.2.1 & everything went well.. except cydia. I opened Loader & tried downloading it. It stopped at about 43% then it says "Completed" or something like that. So, I clicked the home button & my iPhone rebooted. After that I tried opening cydia. Then, yea, it crashes everytime I try opening it. I've restored all over, hard reset, blah. I was just hoping if an official could help me with this. I was almost satisfied until the cydia issue. So, yea. Thanks in advance. (Phew)

I have the very same problem. I have tried every remedy I found in the internet. I don't want to restore and do another jailbreaking again... Please help.

The first thing you can try is to install Cydia again. If the loader doesn't work, use the redsn0w tool and select "install Cydia" (nothing else selected). If that also fails, just restart with a fresh restore of 4.2.1, then GP, then data-restore from iTunes backup and then sync, then reinstall Cydia apps.

Ok. But, what is the redsn0w tool? I've read it on other questions & I don't what it is..
