Various iPhone 6 mockups and concept designs have emerged online like wildfire to satiate in advance the anticipation of Apple's fans.

Majority of the envisioned designs for the next generation iPhone turn out to have round edge designs and an all-aluminum look.

Here is a roundup of the top three mockup designs that have already appeared online:

iPhone 6 model by Mac Fan

The first one was based on precise sketches that first appeared in Mac Fan, which is a Japanese website. It appears related to two previous iPhone drawings showing the latest model in two size options of 4.7 inch and the other in 5.7 inch.

The second one was made by Macityney that shows the smaller version of the iPhone with the power button on its side mounts, right above the microSIM slot.

The last iPhone 6 mockup design was made and published by a Chinese blog called 86Digi. It shows an extremely thin design at 6mm variant with the power button in a new placement as well.

Majority of these iPhone designs lead to the high possibility of the anticipated iPhone 6 to turn out thinner and with rounder edges, according to PC Authority.

On other iPhone 6 rumors, the new chief analyst of ESM-China mentioned that its camera will feature EIS instead of the usual OIS specifications. This is to give way to producing a thinner handset envisioned and expected by most, including the potential of having a brand new 64-bit mobile processor, states The Bit Bag.

Meanwhile, a seemingly irate employee of the Cupertino-tech giant leaked some news via Secret that the iPhone 6 headphones will come packed with sensors to track blood pressure and monitor heart rate.

The upcoming iPhone 6 release date is eyed to happen this September along with the release of the Apple iWatch and iOS 8.
