The only people who actually know are the people high up in Apple, AT&T, Verizon, and any other carriers Apple uses. Customer Service representatives know nothing, the guy was either telling you what he read on a rumor site, or making up a story so you would stay with verizon and be happy.
If that happened apple would have pulled off their best surprise for years. There were pics of parts of the iPhone 4 for months before its release, (putting aside the whole stolen prototype), same with iPads and iPhone 3G.
There has been little credible info about the iPhone 5 out there. September at the earliest.
1. Release iPhone 4 update with minor update, call it iPhone 4S.
2. Introduce iOS 5 and officially launch it a month or two later. iOS 5 will support both iPhone 4 and 4S
But then again, I have been wrong many times in life
I stopped in the Verizon store and that same guy showed me the iPhone 5 and let me play around with it. It's very nice the case is made from a unicorn's horn.
Although extremely unlikely, I suppose it is possible that apple is going to reveal the next iPhone at wwdc and all these rumors about September are to prevent a leak like they had with the iPhone 4.
All that said, there is no way a VZ employee knows anything about the next iPhone.
But yeah I think its really all up in the air right now on a new iPhone release. After last year's leak debacle, I feel like Apple could have something up their sleeves but then again I am doubtful if iOS 5 isn't ready.
If it's true that it isn't really a major upgrade? Why not? I mean maybe a 3.7" screen with a dual core processor and only available in black and everything's fine I guess.
Iphone 5? pffft. I already have the iphone 6 and am testing the iphone 7. Steve and I hang out at Buffalo Wild Wings on friday. Come join us sometime. He likes shoing off the ipad 5. Pretty impressive for a device that is only 1/4 inch thick.
