A new report suggests that Apple is preparing to begin testing its long-rumored low-cost iPhone sometime next month. According to Japanese website Macotakara, the handset will be available in a variety of colors, including Navy, Gold-Orange, White, Gray, Pink, Green, Blue and Yellow-Orange. Only 1,000 units of the low-cost iPhone will reportedly be produced for field tests in June, with consumer production slated to take place between July and September. Earlier reports claimed Apple would offer the device for as little as $99 or $149 from retailers. It has also been suggested that the cheaper iPhone would feature a shell made of polycarbonate plastic to bring the price down.
