iPhone 6 5.5 model using ipad IOS?

[imtom]

I'll be curious to see if they use the ipad iOS on the 5.5 inch phablet, with all that extra screen space maybe the iPhone iOS doesn't look right on a bigger 5.5 screen. Maybe we would see messages more like this on the larger display, who knows.

It would be more optimized for the screen size but not exactly iPad iOS.
