i have had the ipod touch 1g 16gb for about 2 years now and i think it is time for me to upgrade my ipod touch... i feel like my ipod is slow as it lags alot on just about every app i own so i dont know if to get the ipod touch 2g 16gb or the 3g 32gb? i have a few questions i need answering and hopefully you can answer them for me. 1, does iso 4 work on ipod touch 2g? 2, can the ipod touch 2g play games (mainly 3d) without laging 3, which ipod touch is the fastest 4, does the ipod touch 2g and 3g screen get marked up easily? 5, what is the battery life like on the ipod touch 2g and 3g (better than the 1g?) (and how long does it last with games) 6, can you jailbreak the 3g? 7, can you jailbreak the 2g mc model?
