I am looking to upgrade my black Verizon iPhone 4 16g, to the new iPhone 5S. I have the original box, charger, directions, etc. I have heard all the hype about the trade in program that the various retailers are going to be offering, but can't get a straight answer from Apple. Best Buy stated: $100 towards new iPhone. Verizon stated: $100 online, may be more in store. Walmart stated: They would have more information tomorrow. (And they are offering the sale price with contract of 5C and 5S cheaper) Apple stated: They will not know until the day of when they put it through a checklist. eBay: Anywhere from $100-$300. So how are all these articles coming out with the best trade in prices? Can anyone recommend where the best trade in and purchase is going to be for a Verizon iPhone 4? Thanks!
