Sprint has joined the list of retailers accepting an iPhone trade-in with their new promotion in which customers can trade in any older iPhone model and receive at least $100 worth of credit towards the purchase of an iPhone 4S. This promotion applies to any and all new customers, and it is running from May 18th until June 30th.
The company has not yet given details on just how much credit each iPhone model will earn, but since it starts at $100, newer models like the iPhone 4 are likely to bring in even more credit. This move by Sprint is very likely aimed at attracting new customers from other iPhone carriers, like AT&T, Verizon, and other regional carriers.
If you have an old iPhone lying around and really want to upgrade to the iPhone 4S (and wouldn’t mind signing a contract with Sprint as well), then take advantage of this promotion while it lasts.
