I've done a search, no answers came back that apply to 1.1.3. Perhaps my search-fu is weak, but I'll ask anyway and risk the flames. I've got a 1.1.3 16GB iPod Touch, stock but with apps add-on released last month. Serial number indicates it's a week 40 2007 iPod Touch. I'm on a Mac running Leopard, iTunes version 7.6. I synch this iPod Touch, a 16GB iPhone and an old 3G iPod to this iTunes install. If I want to Jailbreak my iPod Touch, it appears I may (or may not) lose my music off of the device. No big deal really as I have it all in my library on the Mac. But once it's Jaibroken, can I re-synch my music/videos/etc back onto the device? Or can I no longer use iTunes with my newly-JB'd iPod Touch? Keep in mind I still use iTunes for the iPhone (it's not JB'd, never will be).
