You don't call a call center directly, you call customer service and your call gets forwarded there, so its no surprise they don't have a direct line. Seems like an odd date to release it, but I do thank you for sharing what you have heard lebowski, leaks are what keep any forum like this alive. Dates change all the time, so there's no reason to say he is wrong, or the Moto leakers are, because the dates are still fluid until they are officially announced, and can change even then (Charge anyone?) .
As for the iPhone LTE, this new one coming soon will not have it. But from what's leaked related to the Apple-Samsung lawsuit strongly suggests this won't be the iPhone 5. All those leaks refer to the iPhone 5 as something coming out middle of next year, with super hardware and an edge to edge screen. Its talked about as the competitor to the GS3, which is obviously not coming real soon. By then, you couldn't release a superphone without LTE, as international markets will be starting to get it, and the radios will be much more efficient. So in fact, the iPhone 5 will have LTE, and this upcoming device will be some sort of hardware revision to the 4, much like the 3GS was to the 3G.
Of course we don't know any of that for sure yet, its just what the leaks suggest. We'll just have to wait and see to know for sure. But that's certainly nothing new to us.
