NextWorth and Target are extending their price lock guarantee for iPhone trade-ins at Target Mobile locations across the US. Through November 5th customers can take in their old iPhone model and get a guaranteed price of $200 for any iPhone 4, $125 for a 3GS and $75 for a 3G. Prices are based on used iPhones in good working order, rather than phones in excellent or flawless condition, meaning most customers will qualify for the full values.
