I just thought it would be interesting to see what you 3GSers are upgrading from, and when you intend to upgrade again. I'm upgrading from a First Generation 4GB iPhone that I bought on July 1st, 2007 for a ridiculous price of $499.99. With my $100 refund Apple later gave me, I got a nice set of speakers for my then-brand-new MacBook Pro. I plan to upgrade again in two years (just like I did with my last iPhone), unless Apple adds some insane new features that I just won't be able to live without. I lived without 3G (no 3G in my area anyway), GPS, and a new case design for a year. So, I plan to hold out for the 2011 model, which should come out as I'm graduating from college. What about you guys?
