Now I cannot create a back up of iPhone in iTunes

[neonbright]

I get this error: iTunes could not back up the iPhone " xxxx iPhone" because the iPhone is disconnected. Of course it is not true, I have it connected, it will sync but not back up. I had old back ups from another iPhone, but I had to exchange it out for this one. I have tried everything I could find on the internet, and all the programs on my iPhone is the same as the old one.

What can be the problem?

3.12, Jailbroken
