Update 2: Here is a forum post by ShackMaster that goes into detail on how Radio Shack carries Sprint refurbished phones.
Update: Just confirmed it myself, and the prices are not bad. Nokia 3585i for $79.99, among others. Sprint refurbs are extremely high quality, so you may want to consider getting one to save a few bucks.
I keep hearing reports of RadioShack selling refurbished Sprint phones. I can’t get any new info on this, perhaps someone would like to chime in here?
