Ever since I downloaded and installed the latest version of Itunes for Windows 7 64-bit, I have been getting an Iphone sync error -25 message. I am using a 3gs with the spirit JB. I never had this issue happen while syncing with the previous 64-bit for Windows 7 version. What should I do to fix this? I wanted to upgrade to the latest itunes version in case I get an ipad for Father's day, so what version works best with a jb iphone and new ipad?
