I purchased an Ipod Touch about a year ago and i was wondering if it was possible to upgrade it to the 2nd generation< possibly by paying a few dollars< thanks
No. When you buy a product, you are buying it knowing that it will eventually be obsolete. If companies allowed you to purchase the newer model for a small fee, they'd go out of business.
BBYMemployee - has a good point. Being the leader of a club at my school, we know that giving people things for a small fee will cause us to run out of money.
