If we already have an iPhone 3G, will we most likely have to extend the plan for another 2 years, or will we simply just buy another iPhone and carry on with our current plan? For all we know, Apple is already thinking of what to do on the next iPhone for next summer for those who bought iPhone 3G almost one year ago when our 2 year contract expires, so maybe we should be smart and get that advantage that original iPhone users will have going up 2 upgrades at once (from original to new one) to save money rather than going up on each single upgrade (from 3g to new one and then next summer's most likely model) that Apple releases and losing money. What do you guys think?
