I have my iPhone 4 with iOS5 tether jailbreak. I was in iFile in the application folder and I saw 2 instances of cydia. Cydia.app and 2Cydia.app where I previously renamed it. Since cydia was working, in iFile I moved 2Cydia.app to the trash and trashed it. Now, I lost The Cydia icon on my iPhone. In iFile I still see the other instance of Cydia, Cydia.app. I tried using redsn0w to run the jailbreak again and install the Cydia icon but that did not get the Cydia icon back. I have tried booting tethered several times and the icons is not coming back. I also tried deleting the springboard.plist from var/mobile/library/preferences/com.apple.springboard.plist. I tether booted my iPhone and it got the loading icon to rebuild the springboard but the Cydia icons did not come back. IFile still shows that Cydia is there. I do not have SSH enabled. How can I get Cydia back?
