Hi, I have the first gen iphone, my contract ends next month. I was thinking about getting the $99 3g iphone, but is it worth the extra $100 for 3gs? Is the internet speed on 3gs better than 3g (without wifi)? There's only two things that made me interested with 3gs, which is the 2x faster, and getting 16gb for $100 more. Do you think those two are worth $100? (I know people will say it's up to me to decide, but I want your opinion, what would you do?) Also do you know the price range for the used 1st generation iphone? Sorry about the grammatical errors, thank you for your time.
