So I have a VZW iPhone 5. I get that Apple and VZW don't support talk and surf at the same time. However, when I pop in a t mobile sim, I can talk and surf. So why isn't there a jailbreak that overrides the CDMA talk and allows LTE surf?

As far as I'm aware of, it's a hardware limitation
 
Yup it's a hardware limitation in the iphone some CDMA phones can do it. But not the iPhone. It's because of how they manufactured the device and the chips they used. It was the main reason I stuck with AT&T after Verizon started carrying the iPhone.
 
You can't have simultaneous talk and data on CDMA, it's the limitation of the CDMA network. The work around for this is to use two antenas one for voice one for data, that's what some other Verizon LTE phones do.

Unfortunately but not surprisingly Apple decided not to add a second antena to the iPhone most likely because it would have cost them few cents more or as they would like you to believe it is either A. A feature most people don't want B. There is no room for it inside the phone or C. It's "a bag of hurt" to do it.

How much you pay for T-Mobile on your Verizon iPhone 5?

I'll bet it's a feature on the 5S.
 
T- Mobiles service is great in my area, I don't use it but some friends do. I'm glad they are in business, the industry needs competition.

for the iphone, it only applies if tmobile has refarmed 3g (1900 MHz). otherwise, you'll get edge.

the exception to this if you get the newer tweaked iphone 5 which can utilize AWS 1700/2100 3G (the one released on april 12th).
 
I didn't bother to reply to the troll. What a fool.

My t-mobile iPhone 5 can connect to LTE, 4g, and edge. Although I thought it was connected to 3g at one point too.

Although LTE was only in the t-mobile store. Haven't seen it since
 

yeah i'm sure, If you think having LTE in 7 cities is considered having LTE coverage by a cell phone carrier then just lol.

Guess what?
They do:D

no, not yet.

lol at troll, you just proved my point in your post, thanks.

T-Mobiles service will depend on two things:

1. Phone
2. Location

When I place my T-Mobile sim in a Nexus 4, a phone that is built for T-Mobiles service frequencies, I get 4G everywhere I go.

When I place that same sim in the 4S or 3GS that I have, I get excellent 4G service at home but it's very spotty and moves to edge speeds in a huge area in my city.

The T-Mobile iPhone 5 will work as good as my Nexus 4 with excellent reception everywhere I go but I have no plans to buy one.

Yes, that's considered having LTE coverage. Is it a good or bad coverage is another argument. So your claim is wrong.

You can say that it has bad coverage but you can't say that they don't have LTE.
 
Are you sure?

It looks to me like a Verizon phone that supports data and voice at the same time would have to be bigger and cost more than the equivalent AT&T iPhone.

I'm not positive, but both Apple and carriers always want to have better tech year by year.
