Buy iPhone 4/3GS From Radio Shack On $50 Discount

American retailer Radio Shack has announced a limited time promotion for iPhone 4 and iPhone 3GS units that will bring these units to customers at a discount of $50. The promotion begins on December 4 and shall run through the week till December 11. The deal is only applicable on new units and not on the refurbished phones and in case it wasn’t obvious enough – you need to sign up for a new two year contract to be eligible for the deal.

The offer details are not over yet. There are more attractive offerings to be had if you already own an iPhone 3G or 3GS unit. Radio Shack has launched a new “Trade and Save” offer that will credit you with $75 and $125 respectively when you trade in one of these devices in return for a new purchase. That means, if you trade in an iPhone 3GS, you can buy a new 16GB iPhone 4 for as low as $24.99 while the 32GB variant will cost you $124.99.

Of course, it goes without saying that these devices that are traded in need to be in working condition and cannot act like bricks.
