What has happened in the past to the price of the old phone, between the media event and the new phone hitting shelves? I ask because I have family members who don't need the latest and greatest. Our mobile share plan makes basic phones the same cost as smart phones, so I want to get another low cost smart phone. I would guess they will have an 8 gb 4 for free, and a an 8 gb 4S for $100. But what happens to existing stock of 16/32/64? If I could get him a 16 GB 4S for $100-150 I could find it worthwhile. After all, I could still sell it when he's done with it and make more than an 8 GB phone would get. Just kicking ideas around and speculating like everyone else. So does anyone remember what happened to the iPhone 4 16 and 32's after the 4S was announced?
