Guys, I bought a SIII in July 2012 and my 16GB MicroSD died on me in October 2012... And on 30th Nov 2012, my phone died!!

It was working fine till 3PM, then nothing............ It won't turn on! Tried everything. The battery is working fine.
I should have listened to my friends...
I have given the phone for warranty repairs, lets hope they figure out the problem and it never happens again!
