Newbie owner of 2nd gen iPod Touch

[k6578]

I've been using Mac and OS X for years. I recently got a second hand 2nd generation iPod Touch from a friend and so now I have the MacBook Pro, iPod Touch and dumb phone combination for college. First time having an iOS device.

The highest my Touch can go is iOS 4.2.1 which means I can't download the apps for Facebook or Twitter. For FB, I've added a bookmark to the home screen and I've set it so that FB emails me (separate address from my personal one) every time there's a notification and that will show up on the Mail icon on the Touch. So far it works I guess.. Any other ways?

And for Notes, there's no way to sync wirelessly is there? So when I sync it with iTunes, where do the Notes go on the computer?

Also, how do you make screen caps?

Any other tips for a newbie? What apps are there that works with 4.2.1?

Thanks!
