Since I don't get an upgrade (Im hoping that will change soon), I am planning on selling my 3GS to make up for the price. When is the best time to sell? I don't want to sell my phone too early and be w/o a good iphone for a while before the new one comes out. Do you think the release of the new one will have a significant impact on the price of unlocked 3GS'? Since the new one is not unlockable, perhaps not? Just looking for some thoughts on this..
