For about 2 days whenever I try to use Siri or dictation on my iPhone 4S it stalls for a while, then goes "I'm really sorry about this, but I can't take any requests right now.....". I tried on friends' phones and they all work. I've tried restarting and everything, my try to restore tonight but Siri uses the server so I don't know why it's just me. Very frustrating.
