I installed the 1.1.1 and used the jailbreakme tiff exploit to install the app installer. I then updated it to 1.1.2 and the used the jailbreak for 1.1.2. Now I cannot sync with my laptop. When I plug into my laptop, the touch turns on to the sync screen and then stops about 3 seconds in. I tried syncing using iTunes too, but that doesn't work either. Is there a setting I need to change? What did I do wrong? Any suggestions to resolve this?
