Just recently my iPhone 4 is having problems retrieving voicemails. The voicemails come in and when I go to listen to it, it acts like it won't connect. The little box next to the message just keeps swirling and swirling. If I wait an hour or so, I MAY be able to listen to it then, but sometimes it takes several hours.
I asked a few friends who have had this issue and it went away for them when they upgraded to OS5, so I did that just now and I am having the same problem with the voicemail.
Can anyone help?
