I have jailbroken device using Absinthe, 2 days back I removed the jailbreak. Now I am not able to connect my iPhone 4 to iTunes. It says "iTunes could not connect to the iPhone because an invalid response was received from the device".
I have tried it on another system and also changed the cable. Problem is as it is. Anybody please help me? Now I am not able to sync it.. :(

Try resetting your network settings

Settings -> General -> Reset -> Reset Network Settings

And try deleting the contents of your mac/pc lockdown folder. Here's the link, follow the steps on "Reset the Lockdown folder".
