Things are heating up in the global smartphone market as new challengers are emerging to Apple's (NASDAQ:AAPL) already widely discussed iPhone 6.

Korean smartphone giant Samsung recently launched this year's edition of its highly popular Galaxy S5. And over the weekend, word broke that e-commerce Ubermensch Amazon.com also has a smartphone of its own in development.

However, one recent storyline regarding Apple's iPhone 6 seemed larger than life, in more ways than one.

Apple's iPhone 6: big and getting bigger
It's widely believed that Apple is planning to increase the screen size for the iPhone 6 as part of the broader form factor redesign Apple commonly institutes on even years.

Recently, one rumor claimed that Apple was planning to segment its iPhone into two different-sized handsets, one 4.7-inch and another larger 5.5-inch phablet. And depending on Apple's commitment to its now two-tiered pricing it introduced with the iPhone 5s and 5c, this rumor would potentially open the door to Apple further divide its key financial driver into yet another set of models.

In the video below, tech and telecom analyst Andrew Tonner breaks down these recent iPhone 6 rumors and gives his thinking as to why it seems unlikely Apple would ultimately pursue this strategy.
