operate from all device

i think, why proponed multiple application for mobile?
Iphone application not good!
Android application not perfect!
Java application not compatible for mobile device or carrier?
lite betfair not complete!

WHY not working for release just application for all device! Operate from browser mobile lite.betfair.com accessible for all device in the world, but complete. For example: possible edit bets unmatched, possible create my markets, possible access in the area my account, possible see the results live game similar in the java application, not disconected login after 5 minutes...

I think just ONE access for all device from mobile browser.

thanks
