Sprint and Verizon iPhone 5 won't allow simultaneous voice calls and LTE data

This probably won't be much of a deal breaker for potential iPhone 5 owners, but we thought it would be good to give you, guys, a heads up, especially now that the smartphone is up for pre-order. Turns out that the iPhone 5 cannot handle voice calls and LTE data at the same time when used on a CDMA network. In other words, Verizon and Sprint iPhone 5 owners will have their LTE data cut off during calls, so their smartphone will have no internet connection unless it is connected to a Wi-Fi network. This limitation won't be present on the AT&T iPhone 5.
Now, this lack of simultaneous voice calls and LTE data probably doesn't make sense to some of you. After all, data will flow over LTE, meaning that the CDMA radio is free to handle voice calls at the same time, right? Well, not really. The thing is that the iPhone 5 uses two antennas for a single call and actively switches between them, depending on which one has better reception. Other smartphone makers use several antennas too, but while one of them is dedicated to voice calls, another one handles data connectivity.
Simply put, the lack of a dedicated antenna for LTE data in the iPhone 5 is in the bottom of all this. Thankfully, as LTE technology evolves, there is hope that the limitation will one day be a thing of the past. Sounds like e good improvement to introduce with an iPhone 5S, don't you think?

no the iphone can handle it the thing is that this is a consumer device. and consumers care about battery life and the phone just working. thats a feature power users would like to have but its heavier on the battery. but thats why there is choices.

Idiots. Did AT&T put Apple up to this? It's not 2010 anymore. I can talk and surf at the same time on VZW even in a 3G area.

This news will increase the sale of iPhone 5 by 200%. now you guys will ask 'how'......... The answer is that, this will make the first gen. iPhone users nostalgic, when they will remember that back in 2007, they couldn't use voice and data simultaneously, and in nostalgia, they will flock to buy iPhone 5. :) So Verizon and sprint will have very good iPhone sale this yr. :)
