I bought an iPhone 3G last year and became a new customer of ATT with a 2-year agreement. My agreement isn't over until next July (2010). Since ATT is allowing early 3GS upgrades, I checked and I am eligible for the discounted price of the 3GS.

If I upgrade to the 3GS with the discounted price does it add 2 years to my current commitment, thus I would have 3 more years with ATT or does it reset my 2 year commitment, so I would just have 2 years of commitment?

Also, what is the penalty if I close my ATT contract early at some time in the future?

Thanks.
