get AppSync 3.1 (allows for you to download games on your computer or ipod vice versa and sync them up with your itunes account, this way it is quicker to download large games ex. GTA or RockBand) I also suggest MIM (Make it Mine) allows you to customize the top bar where the iPod and time are to say anything you'd like (eg. Wizzup is win) and (Navatwo is winrar) I use Rock since it is faster and more lightweight.
edit: to get installous now add the source
