This morning everything was working fine after leaving the AT&T store. Now the ringer is stuck in headphones mode, even without ever using the headphones. This prevents me hearing ringtones and talking with people unless I decide to use speaker phone or wear the earphones around. I have tried numerous things, thinking there may be dirt in the headphone jack. I used a Q-tip, even compressed air. I also followed all of these steps (http://support.apple.com/kb/TS1630?viewlocale=en_US) to no avail. Here's the kicker... I can go into settings and click on a ringtone and it will play! I go back to the home menu and use the ringer volume buttons on the side, and it says "Ringer". Looks promising, but when it locks, or I try to make a phone call it goes back to headphones. I really want to avoid the apple store, but I can't think of anything else to do? Any advice?
