Hi everyone. I recently jailbroke my iPhone 3G (2.1 firmware) and now I have a problem with syncing my apps from my Mac back to my iPhone. On iTunes, I went on the Applications tab, ticked all the apps I want to sync back to my iPhone and clicked on 'Sync'. It started loading as it normally would but then I got this message: I also tried downloading the apps directly from my iPhone from the App Store. This didn't work either. I got the following message: .. but I already am logged in.. Any suggestions? Thanks in advance. Yani.
