Yellow Triangle at bootup A few days ago I bought a Samsung Galaxy S2. But, at phone start up under the Galaxy S2 Logo I see a strange Yellow Triangle. I read a few forum posts found on google, but I have some doubts about this. To be more precisely, what that means? Ah, and yes, at first start up I didn't see this triangle, he appears after I tried to update the phone software from samsungapps.com
