For iPhone returns, you may return your undamaged iPhone with its included accessories within 14 days of purchase for a full refund. Here’s the important part: returning your iPhone may not automatically cancel or reset your wireless account; you are responsible for your wireless service agreement and for any applicable fees associated with your wireless account. Please contact your provider for more information.

Maybe I was thinking of Verizon and the activation fee. I don't know every carriers policy and fees but you would have to discuss this with your carrier to find out the specific fees involved. At any rate it seems 14 days is the limit.
