I am thinking about buying an iphone 3g, but I have a few questions before I do buy it: 1. Does it make sense to wait till January, in case something new comes out? 2. Can you use both an Education Discount and Recycling Ipod Discount on the same Ipod? 3. If I do buy an iphone 3g, and a new iphone 3g (increase flash memory, or decrease in price) does come out, can I swap the iphone I bought for the new one? Thanks for any help you can give me!
