I seem to be getting missed calls and no txts with my iphone 4. It can last for hours at a time and happens almost daily.
I've seen that it can be related to apps accessing data and the voice/txt not cutting off the data transmission? I also read somewhere that it's how Vodafone priorities data over voice?
Anyhow, if I move to XT is this going to stop? It's getting beyond a joke and I get no help from Vodafone - just promises that their iphone team willl 'call me back' but nothing.
