Colorful arc seen in the sky after a rainstorm - I mean Rainbow!!!

Awesome!!! A rainbow after heavy rain is something rare and beautiful to see, however nowadays it's hard to  click a clear picture of sky because of two important reasons:

1. Cellular towers, which you can't avoid.
2. Camera of my mobile is only of 3.2 mega pixel. (When I will get Nokia N8???)  ;-)

Managed to click one without any tower, but still I am not satisfied.
