I am new to doing upgrades to my touch 1st gen. I have 1.4 at the moment, I would like to be able to put games onto my itouch. I need to know how I can upgrade to 2 and higher? I would like to upgrade for free but I am willing to pay. I need to know what each upgrades gives me and is it worth me spending the money. I have been to the itunes store looking for the upgrades but there is nothing there for me. I would love any help from anyone. Thanks
