I have 2 carrier unlocked AT&T iPhone 4 phones. Both are 16gb. My wife and I will be switching to the Verizon iPhone 5 after it is released. Here are my options: - Purchase a AT&T "dumb phone" and a micro sim adapter and try to survive with a dumb phone for a few weeks. This may allow me to get the maximum price for my iPhone 4 as the price may drop after the iPhone 5 release. - Wait until the iPhone 5 is shipped and once I receive it, place the iPhone 4 for sale. Possible for a lower price. Any ideas where to sell it? Craigslist ebay gazelle How much do you think I can get for them? Will there be a difference between selling Pre iPhone 5 release and after the release? I would like to get at least $200 each to cover the cost of the iPhone 5. Is this reasonable?
