Is anyone else experiencing problems with facetime after updating to 4.3? My friend and I both have 4.3 on our iPhones and we keep running into problems when trying to facetime. Sometimes my camera won't activate, sometimes her camera won't activate. Sometimes the sound won't work, and other times the call will immediately end right after tapping the 'accept' button when getting a facetime call. I'm hoping this can be fixed through a software update.
