Apple is preparing to launch a new, less expensive iPhone 4 model that will become available at the end of September alongside the iPhone 5, Reuters reported on Tuesday. Citing multiple anonymous sources, the news organization says that the retooled iPhone 4 will feature a smaller 8GB flash drive manufactured by an unnamed South Korean company. Apple has sourced flash drives for its current iPhone models from Toshiba and Samsung. Reuters also contradicts recent reports that the iPhone 5 will launch in early October, writing instead that Apple is “targeting an end-September launch for the next-generation iPhone 5.” The report restates numerous others that claim the iPhone 5 will feature a larger display, a new antenna design and an 8-megapixel camera.
