Airtel 3G Tariff Review Launched In Bangalore, Delhi, Coimbtore,Chennai, Jaipur,Delhi

Airtel has launched 3G services in Bangalore, Delhi, Coimbtore, Chennai, Jaipur, Delhi. I did not see unlimited data plans in the list (checked few cities) so wondering how do you all think about Airtel 3G plans.

Are they competitive enough? Or BSNL still rules?
