hello all, been nosing around for the past day or so. just got a 16gb 2nd gen. so far it's been ok. it plays music just like my screen broken archos. the pod does have the touchy screen which i like and it is a lot thinner. but i feel as though i'm going to break it it's so small. i have a ton of questions. but i'm sure they've been answered a hundred times i just got to find the right search words. to get the right answers. one question i will ask here to keep the whole noob asking a common question thing........... i see a lot of cool themes for the touch does it have to be jailbroken to use them?
