I've been doing a lot of research into this as I have been having this problem for a while.
So far we have been able to resolve the issue with the outbound calls/sms by changing the APN. Unfortunately, this somehow blocks most of the incoming calls/sms. Or at least it has for me, has no one else had this issue? As I mentioned a few 'posts' ago, I recently noticed that my phone is constantly trying to somehow communicate with the network, even when I'm not using it. Today I came across this article http://blogs.zdnet.com/Apple/?p=740&tag=untagged discussing EDGE and the iPhones inability to receive calls when EDGE is being used. I am assuming that this is what is blocking my incoming calls.
So my question is, if APN is disabled, how is my phone still trying to communicate with the network?
