How to Fix Cydia if It Closes Automatically or after a Few Seconds of Loading Data

If you're on 3.0, or any other version (I have not confirmed this problem on other versions), and your Cydia crashes also immediately or after a few seconds of loading data, don't panic. I have the solution.

1. Open Terminal (If you don't have it, you can get it via Icy. If you don't have Icy, re-jailbreak your phone).
2. Type "su" (no quotes).
3. Type your password. If you haven't changed yours, it will be "alpine" (no quotes).
4. Type "apt-get remove cydia" (no quotes).
5. It will take some time to do its thing, but after a while it will ask you to continue. Type "Yes, do as I say!" (no quotes).
6. After a while it will complete. To get Cydia back, type "apt-get install cydia" (no quotes).
7. You now have Cydia back!
