AT&T iPhone 5 will support voice and data simultaneously
No matter how you feel about the
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."
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.

The email thing doesn't sound like a big deal the way you described it, but a more problematic scenario would be talking on speakerphone/headset with the person sending the email. On Verizon/Sprint, with the new iPhone, you would have to hang up, wait a minute a two, and then call the person back to review the email with them.
Another more likely scenario is getting a phone call while using your phone as a wifi hotspot. If you were using your phone as a hotspot and someone called, you would lose the your laptop/tablet would lose it's internet connection.
Obviously, neither scenario would be the end of the world, but could be pretty annoying, especially in a situation where you were in a conference call or something.
