Hi! I just started having problems today with this. I was on a call & got disconnected. Looked at my phone & the airplane icon was on top??? I never turned this on. Went to settings & turned it off & tried to make phone call again. Disconnected again & the little airplane icon was on again. I powered off & on about 5 times. Powered down again & took battery out. I looked thru the little book that came w/ my phone, but there was nothing in it to help me. Someone PLEASE help! I and, please don't say that I have to do a factory reset & lose all of my ringtones, etc.
