I was using the Pandora Radio app today when I curiously tried to call myself with a landline to see what would happen. It rang a few times and went to voicemail, my iphone never even alerted me of an incoming call and when I exited Pandora, the Iphone didn't even show that I had a missed call. The same thing happens with AOL Radio... when I use other apps like AIM it seems to be work ok. Anyone else having the same problem? Anyone know how to fix it? Thanks in advance!
