I am from bangalore and can confirm that this new scheme exists. Thanks to the first person on this forum for letting us know about the new scheme. it's rather strange that airtel didnt advertise it anywhere! this must be a permanent thing i feel. anyway, i sent an email to their customer care day before yesterday asking them to upgrade my connection to 384kbps and got a call today saying that from tomorrow it would be activted. i hope i am able to watch youtube without pausing now!! if not i intend to take the 750 rupees one instead....i hope they allow me to shift again.
