Can't the iPhone 4 handle a voice call AND a data connection at the same time?

Today, I was slightly dumb founded?!?? :S

I have an iPhone 4 on the O2 network and was making a phone call today.

At the same time, I had to keep a web page open and viewable on screen(so that I could refer to an order number for some flowers!).

However, once the web page was displayed and the phone call actually connected, my iPhone showed up a message displaying 'data connections not possible whilst making this call' (it was an 0845 number - if that makes any difference?!)

If you check out the screen shot - you'll notice that I have the phone call active but NO data connection??!

I thought the iPhone 4 COULD do both of these at the same time?? Or am I missing something?!

The Iphone 4 can do, how it works though is you must be able to use 3G as 2G can not handle voice and data I believe.

I have no problems doing both.
 
If it was on an edge network then it can't do voice and data at the same time but on 3G it can handle it. To my experience anyway.
 
Works with AT&T, no problem.

Doesn't work with Verizon model. Weak.

Is O2 GSM? Should work then.

Of course, assuming you are using 3G network.
 
You have to have a 3G or wifi connection to do voice and data at the sometime. If you have a GPRS or edge connection you can't do both.

I have never heard of the 02 network.

If it is a Verizon phone it works only when in wifi mode.
 
It looks like you were using "Edge" since the "edge" indicator always goes away during a call.

o2 UK obviously it is not a verizon phone. This kind of 90's technology is more or less a US exclusive.
You should be able to do both as long as you are on 3G.

Actually, CDMA is newer technology than GSM.

Pssssst.......there are other networks outside the U.S. :)
 
i am having the same problem with my 3GS. My phone has 3G signal and when someone calls and i pick up the phone then it will lose the 3G signal. It has been like this for a year. If i use hands free to answer calls then the 3G signal will be there.

There are other places other than US in this world. No offense but it always Americans. lol
 
It all depends on your carrier, at least here in the USA
VZ doesn't, ATT does. I have no idea how it works with any other carriers that support the IPhone.
I did notice the UK on the upper left corner of your screen.

VZW: CDMA

CDMA ≠ simultaneous voice and data
GSM = simultaneous voice and data

VZW = only carrier to have the CDMA iPhone.

So .... that's a limitation only by VZW.
 
I am guessing you are on O2's GPRS or EDGE network.
You can only do voice and data at the same time if you are on a 3G network.

Fixed;)

GSM = Raw GSM, GPRS(General Packet Radio Service), and EDGE (Also known as EGPRS)

UMTS = 3G Evolution path of GSM. It is the basic base of HSPA services and using the term UMTS more correctly refers to 3G technology in relation to GSM although HSPA is becoming a more common term.
 
It's amazing how stupid the average GSM user is. Every one of them has put out incorrect information only to be set straight by another Verizon user.

Its not just Verizon users making corrections or AT&T users being "stupid" so lets not make too many generalizations :) My main point is there is so much misinformation about the technology behind the devices. You don't need to understand the encoding scheme's of the CDMA2000 air interface but I mean don't post crap unless your sure. Me I know a good amount about the tech because its cool others may not and that's fine, but don't post without research and valid info. If I ever doubt something ill put a "(?)" after it or say "Someone help me out here I might be wrong..." and thats it. Not everyone needs to be "a genius" but my concern is someone will do a search on here and find a post with the wrong data and won't properly learn something.
