Apple's suppliers may be experiencing a bump in the road at a most inopportune time and the iPhone 6's supposed mid-Sept. released date could be in jeopardy.

Unnamed sources told Reuters exclusively that Apple's supply chains are rushing to get enough screens together for the new handset. The supply chain had to be halted at times in June and July in order to rework the smartphone's backlight.

The sources did not say if that specific hiccup would delay the rumored Sept. 9 unveiling event and the release that is expected to come a matter of weeks later. The sources said that Apple wanted to alter the way they develop their backlights in order to produce a thinner-than-ever iPhone.

The sources also said the 4.7-inch iPhone 6 went into production ahead of the 5.5-inch handset, supporting rumors that consumers will see the latter hit the market a time later. Reuters acknowledged a scheduled media event for Apple and reported the tech giant will unveil both models, though they are not guaranteed to be released together.

In going from a two-layer backlight film to single-layer one, Apple reportedly lost brightness, causing the suppliers to change back. Production time was lost nonetheless, but the sources indicated the suppliers are working to recoup.

"Currently, there's a small shortage in supply of a specialized component for our communication devices," a spokesman for Pegatron, a supplier that assembles iPhones, told Reuters. "This kind of problem regularly occurs and the impact on production is negligible."

Apple may also be readying their first batch of iWatches, Forbes noted, the smart watch is has been rumored to be releasing this year. While the iWatch may not be unveiled in the coming weeks, it could hit shelves in time for holiday shopping, especially since Google and Samsung already have smart watches on the market.
