A dual-head vibration motor obtained by iLab Factory may be a part for the increasingly-rumored low-cost iPhone, says Japanese site Macotakara. The site appears to imply that the dual-head motor is cheaper than the single-head, counterweighted motor in the iPhone 5. The new part is however similar to a motor linked to the iPhone 5S, which may mean that one or both reports have misinterpreted which product it's intended for.
