If you haven't gotten an iPhone yet, or would like to grab one, now is your chance, they've just been dropped in price at various retailers. Target and Radio Shack were the first to drop the prices on Apple's iPhone, but they've been followed by Best Buy, Sam's Club and Sprint.

Best Buy and Sam's Club have reduced the price of the iPhone 4 8GB model to $50 on a new two-year contract. Sprint does things a little differently, where they're offering "at least" $100 off a new contract on the iPhone 4S, with the exchange of any prior iPhone. Best Buy's offer isn't just an in-store offer, their website has a bunch of new and refurbished iPhone 4 units from $50 and under.

Sprint's trade-in offer starts on May 18, with no other details available on whether the $100 off is a fixed price, or what would qualify a buyer for more credit toward the purchase of the new iPhone 4S.
