• Answer:

  First try reinstalling SBSsettings from Cydia. You can find SBSsettings in Cydia's search bar. RESTORE TO 5.0.1: If you can't reinstall springboard, you probably would want to restore to the same firmware since you have an untethered jailbreak. A regular restore from itunes will update firmware and baseband. Here is how to restore to 5.0.1 so you don't lose your jailbreak. You'll need the latest version of redsnow http://www.redsn0w.us/2010/03/download-direct-links-jailbreak-guides.html the latest version of tiny umbrellah http://thefirmwareumbrella.blogspot.com/ and a 5.0.1 ipsw. FOLLOW THE INSTRUCTIONS EXACTLY AS STATED. 1. Back up all your apps in itunes and your cydia applications with your app of choice. 2. Go to http://www.iphonefirmware.com/firmwares-download/ and download the 5.0.1 firmware appropriate for your device. 3. Open tinyumbrellah, plug in your phone, and save ssh blob 4. Go to redsnow and click extra features. Click "custom ipsw" and select the firmware you just downloaded 5. Once IPSW customization is done go to redsnow and click pwned dfu mode. 6. Follow the instructions on screen 7. Go to tinyumbrellah and turn on tss server. 8. After creating custom ipsw, you'll notice another firmware file that begins with NO_BB. This means that there is no baseband upgrade attached to that firmware. Go to itunes. hold shift (if you own windows) or option (if you use mac). While holding the key click restore. 9. Load the ipsw that begins with NO_BB. DO NOT use the original ipsw 10. Wait for restore, 11. You will get an error but don't worry about it. It's normal. You will notice your phone's backlight is lit up but has a completely black screen 12. Go to tinyumbrellah and click fix recovery and you should be set. Most of the time you will still have all your apps and jailbreak still there but now with 5.0.1 again. If not then rejailbreak LAST RESORT: If that does not work, and in desperation you are willing to do a full itunes restore even if it will update your firmware and ruin jailbreak. Follow the instructions under the "blocked by configuration" heading in this article http://support.apple.com/kb/TS3297 This will restore the network settings in itunes that tinyumbrellah altered so you can restore through itunes again.
