No shortage of rumors this year either, it seems. This one from Bloomberg says that Apple's new iPhone is delayed due to last minute changes to the screen size. They say we can expect a display that is one third bigger than the current iPhone 5.
Same reason they may be breaking into the low cost iPhone realm, they see a need that is being fulfilled by someone other than them. Bigger phones are becoming the norm, why not at least offer another option to cater to those that are seeking a bigger display. I'm not due for an upgrade until next Oct and by then I would definitely upgrade to a larger screen if it's an option.
I wonder if these so called "low cost" iPhones are an effort by Apple to created a ghetto boobie friendly phone that is resistant to boob sweat.... You know? I see women stuffing their phones on their bras with half the phone sticking out, gross to think of boob sweat greasing the screen and such lol
