RadioShack is offering a $30 discount on all of their AT&T high end smartphones which obviously includes the iPhone 4S and iPhone 4, starting Sunday and running until December 17th. The sale will bring the iPhone 4S 16GB down to $170 0n contract and the iPhone 4 16GB to $70 on contract. Also, if you use Radioshack’s trade-in program you can get the phones for free and even have some extra credit left over. Head over to your local store to take advantage of this sale.

Update: Word on the street is that Target is going to give $25 back on an iPhone purchase. (Thanks commenter)
