I have an iPod Touch 2G, non MC version. I'm currently very happily running 3.0, but I want to use the new Netflix app, which requires 3.1.3. This iPod has never been jailbroken. Is it possible to upgrade to 3.1.3 or even 4.0.x and retain the possibility to go back to 3.0 if I decide I really don't like it? If yes, how would one go about it? I've been reading through this sub-forum and have already learned a few things, but I'm new to hacking my iPod so there is a lot of terminology that I'm still unfamiliar with. I have no problem looking stuff up, but at this point I'm not yet sure what to look for. If anyone can help point me in the right direction I'd very much appreciate it. Thanks!
