I have no disk space on Macbook Air to install Xcode, finally I found this by google:

Activate it on Windows computer, no jailbreak&xCode request:

I'm using iPodRobot PC Transfer, the only one that I found can auto against iTunes's auto sync!

I recommand iPodRobot pc transfer, all you need do is run it, connect your iPod and press a button.

Why the links are all error?

Try Tube Explorer, help you search, browse, download and convert YouTube and other online videos in another way:)
