Hey guys, for some odd reason. My SMS notification doesn't pop up anymore. So I don't know when I'm getting text messages. Neither does it sound off or vibrate when I receive texts. This suddenly happened a day ago, before working fine. I read that it maybe dirt in my headphone jack but I cleaned it out and still occurs and also tried restoring all settings on the phone. I really don't want to restore thru itunes only as a last resort. Any help is appreciated!
