Apple has reportedly placed an order for 15 million iPhone 5 units with Chinese electronic manufacturer Pegatron. Pegatron’s plants underwent a major expansion in 2010 and 2011 to accommodate Apple’s supply needs for the current iPhone 4 model, so the company had been seen as a likely candidate to receive orders for Apple’s next smartphone. Referring to the handset as both the iPhone 5 and the iPhone 4S, DigiTimes reports that shipments are scheduled to begin in September. The report also states that the upcoming iPhone refresh “does not seem to have any major update from iPhone 4.” Conflicting reports suggest that the next-generation iPhone could either be a major upgrade or an incremental update packed in the same case as the iPhone 4.
