I have a first Generation iPhone I am planning to sell, now that I have finally updated to an IP5. I hung on to the original box but after looking every where, realize it must be in my storage unit. This unit is not near by, about 40 minutes each way. Does the box add enough value to make it worth going to get? (There is also the chance I actually threw it out during a moment of packing stress) It will probably cost me about $15 in gas... Thanks.
