Trade in your 3GS for an iPhone 4 at Radio Shack
Now through July 25, Radio Shack is offering a $200 Gift Card for an iPhone 3GS in working condition that does not have a broken screen or water damage.
If you’re not in a hurry, you should try selling it on eBay or Craigslist. You could get more for it, but don’t be fooled by the completed listings on eBay with unusually high “sold for” prices. The vast majority seem fraudulent to me.
