Hi, I have a 3gs with OS4 on it, which i recently JB with the website method. I have downloaded apps onto my phone via installous and when i go to itunes and sync, it deletes all those apps. I have tried and stopping the sync, and then choosing: "Transfer purchases from" and it works with some of my jailbroken apps, but not all. The ones that dont transfer over to itunes dont stay on the phone. Also i noticed that all my folders on the phone disappear and i have to keep organizing all my applications (major pain). Any ideas?
