Need Help!! A couple of days ago I noticed that I was not getting any sound from my phone. I've checked the the sound profiles and everything is fine. All other functions of the phone work perfectly (email, twitter, facebook etc) but no sound. No ringtones, alerts, text tones, nothing. I'm running OS 6 latest version. I downloaded it a while ago. I have had no problems with my phone up until now. Please, please help.
