error message shown in iTunes "The iphone could not be restored. An unknown error occured (-1)."

There is no "software upgrade" button in general setting of the phone menu.

Current Software version : 2.2.1 (5H11)

is itunes the only way i could get an ios update?

Thanks for help.

iPhone 3GS, iOS 2.x
