Hi there, I just got my new S III a couple of weeks ago after having previously owned an S I. I have transferred all my apps to my new phone by going into Google Play > My Apps. Your purchased apps will be stored here and you can install, uninstall or re-install all your apps to your new phone. I'm a bit of a newbie here too, so I'm not real experienced, but it worked ok for me. I think if you have kept the same phone number from your old phone, you should be able to transfer the apps no problem. I'm sure someone will correct me if I'm not 100% correct here.
