iPhone 3GS for $99 without subscribing to a particular service after jailbreaking?

Let's not talk about iPhone 4 here. I can't seem to figure out the iPhone subscription plan. It's apparently very different in the US than in India.

My question is: Can I buy the iPhone 3GS for $99 in the US and jailbreak it so that I don't have to pay for the 2 years subscription of the carrier? (or at most pay for the month I buy it). US iPhones aren't tied with Indian carriers. Indian iPhones aren't tied to any carriers but they're much more expensive.

 

No, it is only $99 in the US because it is subsidized by AT&T

Also, I recently sold my old 16G iPhone 3GS to a friend for $200. It was not jailbroken.

 

Maybe, but it was in "new" condition and he's not using it as a phone but as an iPod.

 

What exactly does two year subscription mean in the US? There's nothing like that in India.

 

A 2 year contract for cell, data, SMS, etc. service.

 

I asked someone who lives there and you can't. You might do anything you want to that iPhone but you'll have to pay for the service.
