3G no longer staying connected during calls
I'm not sure when this started, but I noticed yesterday that when I receive a phone call, 3G service is dropped for the duration of the call. later I was in an area with 4G coverage and tried making a phone call while using the internet, and 4G was not dropped during the call. So for some reason this problem seems to only be effecting 3G. Does anyone know hat could be going on?

Edit: From the searching I've done, Sprint's systems don't allow it. You can be on 4g browsing the internet and then 3g handles the phone call. Another scenario is you can be WiFi on the internet and then 3g will handle the calls.

Ever notice how the AT&T iPhone commercials like talking about how you can browse the internet (3G) while being on the phone? That's because you can't do it on CDMA (Verizon and Sprint) networks. So no, it was never possible to use 3G data while talking on an Epic.

I guess it all makes sense now, especially after having used the Palm Pre for a year and a half and coming up against Sprint's limitations re: using data while being on the phone. To be honest, I feel a bit silly for not having realized that the Epic was under the same constraints as far as 3G is concerned, and I'm not entirely sure how I didn't realize that you couldn't talk on the phone and use data at the same time until last night. Hell, I've had the phone for three months...sorry, folks.

Ahhh give it another few months-6 months at the rate Sprint and other carriers are adding 4g coverage the 3g limitation won't even be an issue anymore for most customers.

How often do you really need internet access while talking on the phone? To me worst case scenario is you just hang up and call them back right after you've accessed any information. It just seems way overblown as a feature of AT&T.
Switch to AT&T so whenever you need to scroll through a list of carriers AT&T is first. Don't waste precious seconds scrolling all the way down to Sprint or Verizon. Definitely worth having to pay more for data caps and network congestion.

I just did a short test on my Sprint Epic 4G, and I can say for sure that you can talk on the phone while surfing the internet if you are on 4G or wifi.
With that being said, I tried the same test call and tried to surf the internet while on 3G and I cannot surf the internet.
So even though Sprint's CDMA 3G network can't technically handle phone calls and surf the internet in my test examples, if you are on 4G or wifi, then you can do both.
Thats all I need for the amount of times that I would use the "dual feature" of phone and data at the same time - at least it can be done. :-)Samsung Galaxy S3 (tweaked and rooted)
