Cydia Reorganizing after Jailbreaking with Blackra1n

This problem where Cydia says, "Reorganizing, Will automatically close when done" is caused by installing Cydia and Icy at the same time from the Blackra1n app, but it is easily fixed.

DO NOT UNINSTALL THE Blackra1n APP UNTIL YOU ARE SURE YOUR iPHONE OR iPOD IS WORKING PROPERLY

Simply download Rock from the Blackra1n app, and set up a Rock account (if you haven't already).

Search Rock for Cydia Installer.

Install (or re-install) Cydia.

Restart (not respring) your iPhone or iPod Touch.

Open Cydia, should work perfectly!
