I just got a 16GB 1st generation iTouch. How many hours of video can it hold?

I am planning to buy an itouch and was wondering if anyone knows if the prices may drop within the next month or two. Because otherwise I have bad luck where I will buy something then see is like $100 or more cheaper within a week or two.

I just recently got an iTouch as a gift and I never used an Apple portable product. I used my aunt’s computer as she and her husband are iPod savvy to sync and upstart my iTouch. They supposedly say that I have to sync it to my own computer but all the things in it from before hand will be deleted. Is this true?

I’m not sure if you upload the pictures or they’re already loaded on the app but basically the app was that the picture of this ladys butt shook when you shook the itouch/iphone (not the whole picture like other apps i’ve seen like this).
Thanks!

I am not sure if i should jailbreak my itouch because ive heard of some peoples crashing. But, what i want to know is what the advantages of a jailbroken itouch are? Thanks!
