It acts as if it is but it doesnt no error messages just nothing new is added to the iphone i tried manually manage and it works. What should I do?
What exactly are you trying to sync?
Well, it sounds like it used to work. So, what have you changed, software or hardware? Any new apps? Any type of AppSync from cydia, anything like that?
Does your mac even recognize the iPhone, or is it just iTunes not recognizing it? If it's just iTunes, you could try uninstalling and reinstalling it. About the only thing I have for you unfortunately.
