Someone has talked vigorously about this update to the Ipod Touch. but what will it do? if everyone currently jailbreaks, then what will an official tool do? will there be better or more powerful apps or is it just hype? SDK is software development kit, right? its a tool for creating programs ipod touch? then what will be able to see? will it change anything? I currently have an Ipod Nano first gen. I dont know if I should get an Ipod Touch. Im worried about lifespan, price and if I really would need it. it sure looks cool. will there be anything useful software in store for the touch in the future? perhaps something that has something to do with this SDK?
