Annular Solar Eclipse

"Should I buy the eclipse glasses ?" I kept asking myself yesterday, but I didn't get it. While I was watching TV this morning, a man on TV said it's OK to see it with sunglasses. I grabbed my sunglasses and left my home ealier than usual. I saw a few people were looking up the sky with the eclipse glasses near my apt.  I also stopped at the place where I found many people. I could see it with my sun glasseses, and it was totally OK. I saw many poeple were taking a picture with their cell phone. I didn't think it is possible to take the picture with it, but I also tried it. Here is the annular solar eclipse I saw this morning... I still don't get it how they could take a picture with their cell phone. Do they have any special tool???

Just before I checked the website "National Astronomical Observatory of Japan," and it said " DO NOT see the solar eclipse with sunglasses!"..Oops...
