Target is poised to drop prices on iPhones in what could be a sign of clearing stock ahead of a new model. Separate scoops have both shown the retailer dropping prices by at least $30 on iPhones depending on the carrier. Verizon iPhones will get the steepest drops, which in Phone Arena's leak saw prices going down to $150 and $250 for the 16GB and 32GB iPhone 4 models respectively. AT&T devices would unusually cost $10 more, Engadget saw, although the iPhone 3GS at $20 would be one of the cheapest stable prices for an iPhone to date.
