I just got the new iPod touch with the camera; not sure what generation it is, as I'm not that tech savvy. But my mom refuses to get wifi in the house so I'm left without it, therefore my apps are rather useless... So I was wondering if there's any possible (easy!) way to connect my ipod and get a working internet connection through my computer, with a USB plugged into my ipod ? I have a mac computer btw
If your Mac has an internet connection, and it has built-in WiFi (only some MacPro's and some very old Macs don't) then you're fine. To use WiFi, you need a WiFi router. What your mother means is that she will not buy a WiFi router, but the Macintosh can actually serve as a WiFi router just fine.
First do a search on Google for "Mac WiFi without router", there are actually a few Youtube videos that will show you what to do. That way you can set up a WiFi network at home without buying a WiFi router. Next you need to tell the Macintosh to share the Internet, you do that by turning on "Internet Sharing" in "System Preferences" / "Sharing" on the Macintosh. Set your iPod Touch to connect to that network, that's it.
And forget about the "jailbreaking" that was suggested. It won't help you. It cannot possibly help. You need a WiFi network connected to the Internet at home, and the steps above will get that. With a WiFi network, the iPod Touch will get internet access just fine. Without the WiFi network, jailbreaking is not going to help you at all.
