After uninstalling MobileInstallationPatch, My phone locked up..and it was an iBrick for a little while... If this happens to you... FOLLOW THESE STEPS!! BEFORE WE BEGIN 1.First Make sure YOU ARE NOT Connected via USB to your Mac/PC 2.Make Sure iPhone is OFF (Hold Home and Sleep/Wake button in unison for about 5 Seconds) Step 1: Turn Your iPod/iPhone on and LEAVE IT ON for about 15 minutes until the Screen Dims and you see dimmed boxes at the bottom of the screen. BOXES ONLY HAPPEN WITH SOME BOOT SCREENS Step 2: Turn the iPhone/iPod OFF Step 3: Then Turn it on. (DO NOT CONNECT IT TO YOUR COMPUTER YET) and in EXACTLY 5 Seconds Connect it to your Computer. It should boot up and show your Springboard. *******NEW*** METHOD 2: Must have ssh installed 1. turn ipod or iphone off 2. connect cable 3. turn on ipod iphone 4. listen for ding dong (window) or what ever the mac sound is 5. ssh to your ipod iphone 6. goto /var/mobile/ 7. rename Applications to Applications2 8. wait 5 second and your springboard will pop up 9. now rename Applications back and restart I personally had to restore my 2G 2.1 completely because of that MobileInstallationPatch... Be sure to back up your cydia apps with APTBackup, and Backup everything onto itunes RIGHT NOW!!.... just incase.. hope this helped anyone out!!
