I am using Downloader 1099 Plan [my speed was 512 KBPS], and my speed has been doubled to 1MBPS as of today. I called up Airtel Customer Care, and they told me that the speed will remain 1 MBPS permanently and the fair usage policy will remain the same, i.e. 100 GB per month.So, the new Fair usage policy is only for new customers, older customers will be having their previous fair usage limits.P.S. I live in Chandigarh
