Recently, a big report from South Korea claimed to know everything there is to know about Apple's next smartphone release, presumably called the iPhone 6. The report is quite detailed, but how accurate is it? Here is the breakdown of the latest iPhone 6 rumors, so you can determine whether or not the report is worth the fuss.

Recently, analysts from KDB Daewoo Securities Research, a South Korean firm, released a report on the iPhone 6. According to BGR, the firm "is known for having inside sources that have accurately foretold companies' plans on numerous occasions in the past," so the report is worth taking a good look at.

Some of KDB's report coincides with popular iPhone 6 rumors.

KDB's maintains the popular "phablet" rumor, which claims that Apple will release two phones, one of which will have such a large display size that it will be considered a phone and tablet combination. The report says that one phone will have a 4.7-inch or 4.8-inch screen, while the larger model will have a 5.5-inch display.

In addition, the report says that one iPhone will have full HD resolution at 1,920 x 1,080 pixels, while the phablet model will have quad HD resolution at 2,272 x 1,280 pixels.

KDB Daewoo Securities Research seems to confirm realistic iPhone 6 rumors, but some of its other claims call its reliability into question.

Contrary to most reports, KDB says that the upcoming smartphones will run under iOS 7.2. This rumor is raising eyebrows because Apple tends to accompany its iPhone launches with a new iOS (see the launch of iOS 7 with the release of iPhone 5s and 5c). MacRumors even claims that development of the iOS 8 is in its early stages. The upcoming operating software is rumored to have better Maps and a Siri API.

KDB also claims that Apple's upcoming smartphones will feature indium gallium zinc oxide (IGZO) technology instead of low-temperature polysilicon (LTPS) technology, which is featured on today's iPhones.

Some question the likeliness of this sudden switch.

"...the claim of IGZO over LTPS raises some doubt given that LTPS offers better electron mobility and thus greater efficiency than IGZO. IGZO is starting to gain popularity in larger devices such as tablets due to technical limitations with creating LTPS displays at those sizes, but LTPS remains the preferred technology for many high-end smartphones," MacRumors reports.

According to the KDB report, Apple will releases its newest smartphones in the second or third quarter of this year. Other rumors suggest that Apple will debut the iPhone 6 at the Worldwide Developer's Conference in June. Based on the company's release patterns, Apple will likely release new phones to the public in the fall, one year after the release of its newest smartphones, the iPhone 5s and iPhone 5c.
