If you’ve been on the fence for the last few months whether or not you should upgrade your old iPhone 3G/3GS to an iPhone 4, Target has a new deal that should help push you over the edge. Starting tomorrow, February 6th, and running through February 12th, Target will give you up to $100 for a 16GB iPhone 3G and up to $200 for a 32GB iPhone 3GS. Notice the “up to” verbiage meaning your actual bounty may be a lot less. Also to consider, you’ll need to sign a new 2-year contract. Nevertheless, picking up your iPhone 4 at Target over the next week could result in absolutely no money spent on your part. Sounds like a deal to us.
