Draw Something App for iPhone and iPad

My friend from Facebook mentioned the DrawSomething App for iPhone and iPad.
Since I have downloaded it, I have played it over and over with friends to guess what they are drawing.  I thought this is a really great fun game which is so simple to play.
It is a good thing sharing and drawing with other people even though they are just simple sketches.

I was a bit surprised to see that IGN.com saying 'In less than two months, OMGPOP's Draw Something has been downloaded more than 50 million times since 24th February 2012.'

Players can upload their drawings to www.artofdrawsomething.com so others can see it, rate it, leave comments, and vote.
