AT&T iPhone 5 will support voice and data simultaneously

No matter how you feel about the iPhone 5 that was unveiled this week, it's an interesting smartphone to most people. However, we're learning that the phone can't support cellular data and voice calls at the same time on certain 4G LTE networks.
Specifically, the iPhone 5 will be unable to handle simultaneous voice and data use on Verizon Wireless and Sprint versions of the device. This is due to a limitation in the CDMA specification that those two networks use. However, some 4G LTE smartphones on the Verizon network will allow users to make voice calls and use data connectivity at the same time. The iPhone 5 is unable to do this due to design decisions that Apple made.
“The iPhone 5 is designed to allow customers to make voice calls on the Verizon Wireless network and surf the Web on Wi-Fi,” Verizon spokeswoman Brenda Raney said in an e-mail. “It was an Apple decision." 

The New York Times reports that when users place a voice call while connected to 4G LTE network the phone call the defaults to the carriers older second or third-generation networks because LTE networks can't support voice calls at this time.

The reason AT&T iPhone 5 buyers can place phone calls and use data at the same time is because both of those functions roll back to the older AT&T 3G network, which is capable handling both simultaneously.

By my math... iPhone 5 pre-orders sold out in one hour. iPhone 4s pre-orders sold out in 20 hours and actual sales from those pre-orders was 4 million. So doing the math... 4 million divided by 20 hours = 200,000 units per hour. So I will guess that they had 250,000 units for sale on the high end. I can actually believe that this quantity will sell out in an hour.

There's a ton of rumors that Apple has short supply - rightfully so considering the new silicon dual core cortex A15's inside. The inclusion of the A15's actually surprised many of the 'Apple' folks across the interwebs. Many Apple fans thought there would be A9's or quad A9's given the quantities needed for the iPhone 5. There's just no way that Apple can have millions of these devices already made powered by such a new chip. No Way.

And they didn't!

Custom Apple SoC. People expected that the only way they could have squeezed that level of performance combined with that battery life and reduced core size was with the Cortex A15. Nobody, Anand included, considered that this could have been custom.

In hindsight this makes sense. I didn't think that Apple could get the volume of A15s that they needed at this time, and obviously they couldn't so they went off with their own optimized version of existing architectures.
