If you don't have Airtel Live Settings, SMS "LIVE" to 2567.
If you already have, follow the steps below:

Go to AirtelLive Home Page. Then go into Music or Games section. Then select some music or game. You'll be taken to the page where there is Description and Download Link.
Note if you click on the download link there, you'll be charged and then you'll have to sit and cry. So don't click it.

Now If you see below the Download link, There will be ratings and "Change" link to change the ratings. Click on the Change link. In the next page, you'll be asked to download first before rating it. Don't click on Dowload there.

Now Bookmark that page. Then Edit the address of that bookmark titled "Rate the content". You'll find something like this in the address &id=xxxxxxxx&d=

Remove any number between those &id= and &d= then type this number: 1499769
like &id=1499769&d=
Then save the bookmark and open that bookmark.
Then click on Download. Enjoy!
But be careful. You have to follow these steps careful otherwise you'd have to whine.
I downloaded tons of games using this technique on Nokia 2600c

I think this trick will work as long as it doesn't get to the ears of Airtel People.
