After weeks of mounting hype, the first Android handset has finally gone on sale in the US, along with the launch of the Android Market application store.

All games and apps are free for now, but Google has confirmed that when developers do start charging, it won't be taking a revenue share.

Instead, it will payout 70 per cent of an app's revenue to its developer, with the rest going to operators and billing settlement fees.

What's more, it's perhaps the most open app store yet, in that developers pay a one-off $25 fee to upload an application to Android Market, but don't then have to go through any further approval process.

As we've previously reported, the lack of paid downloads has meant mobile game publishers are taking a cautious approach to Android for now.

However, besides the previously announced Bonsai Blast (Glu) and Pac-Man (Namco Bandai) freebies, Glu's Brain Genius Deluxe and Gameloft's Bubble Bash are also apparently live on Android Market now.
