I just opened Cydia and got the complete upgrade/essential upgrade message. I chose "complete upgrade" which updated both the Cydia installer and ********** 4. Now Cydia won't launch at all. Any thoughts on what happened/how to fix this would be appreciated - thanks.
I bet it might have something to do with the starred-out software you posted. Probably the software used to install IPA files without DRM.
Please refrain from discussing programs that enable piracy... and in this case, my gut tells me that that program is the source of your trouble. SSH in and try removing the program manually (/Applications/You-Know-What most likely). Restoring your firmware will work, but at the cost of, well, restoring your firmware.
