Despite claims to the contrary, it’s pretty much all but confirmed that Apple is working on a bigger iPhone. Previous reports had pegged the launch of this larger iPhone for next year, and a new report further corroborates the story.

AppleInsider says a recent report from Jefferies analyst Peter Misek found that Apple is indeed planning on launching a larger iPhone. The new device will reportedly feature a 4.8-inch screen, similar to the display found in rival Samsung’s Galaxy S IV. What’s interesting about this latest report, however, is that Apple was reportedly trying to get the bigger iPhone out this year before it ran into supply issues.

Misek’s report found that Apple tried to bump the phone into an October launch, but recently ran into trouble with its suppliers. They’re reportedly having trouble scaling the 4-inch display of the iPhone 5 to a 4.8-inch display. The issue has caused Apple to cancel its plans for a launch this year, and wait to launch the larger iPhone next year.

So, if Apple was planning on launching a larger iPhone this year, why did Apple CEO Tim Cook defend the size of the iPhone 5 earlier this year? Misek believes that Cook was trying to downplay any rumors of a larger screen size to keep people from waiting for the next iPhone instead of buying the iPhone 5.

Beyond display size, Misek’s report also features some details on what we can expect hardware wise from 2014’s iPhone. Apple is reportedly skipping the 28nm fabrication process entirely to build a 20nm processor that will feature four to eight cores instead of the dual-core now found in the iPhone 5. 2014’s iPhone may also feature an OLED screen, which would allow Apple to make the device thinner and less power hungry.

All of this is rumor for now, but it’s not out of the realm of possibility to see a larger iPhone in 2014. What about 2013 though? Will we see any major changes to the iPhone 5S that’s rumored for this year? All current rumors point to Apple not making any significant design changes, but this year may see the release of a cheaper, plastic iPhone designed for China and other emerging markets.
