Problem: when I receive sms there is no sound or vibration!
I have an iphone 1.1.1 for some unknown reason today when I received a sms my iphone didnt perform any sound or vibrate or anything! it was as if I havent received anything. When I go to Settings-Sounds- New Sms and tap over Tri-tone, glass, bell etc. there is no sound produced. When I hear music or a ringtone for incoming calls they sound wthout a problem. It seems just to be something wrong with my received sms.
Thanks in advance.
