I hate to post things but I couldn't find this one. I've had a real hard time with 2 of my computers in the last month/2 months. It has caused me to constantly switch back and forth. I have all of my music on my computer (a lot). I want to update it on this computer officially, I've checked everything and I don't plan on having any problems for a while. Is it possible to erase and sync without deleting all of the apps? I have a good 40 apps which I use every single one of. I would hate to have to do the whole jailbreak thing again. I'm not sure if it does even delete other things on the iPod please correct me if I'm wrong. Cheers.
