Upon downloading the 3.1 software update... iTunes crashed on me multiple times (while viewing the photos tab in iTunes for my iPhone.. already sent this feedback to Apple)... so iTunes 9 is bugged. So, I then opened iTunes again to redowlnoad the 3.1 software update (which went very quickly... I'm assuming because the first 200 MB or so had already been downloaded so they just breezed by when downloaded again) and my Iphone updated. Now, I can't make any calls... as in there's no ring when I call somebody. I can text though. Is this an at&t issue or my phone's software?
