A better idea for all u ppl who have laptops with bluetooth and a cellphone. and don't want to invest in data cards opt in for a GPRS data plan. use the bluetooth/IRDA/Cable to connect ur phone to the laptop. its Rs. 500 for UNLIMITED in UPE form Hutch and for Rs. 600 from Airtel. Yes, the speed is considerably lower- i get roughly 7-12K only. but its Unlimited! and good for casual surfing and office work. (E-mails W/2-6Mb attchments etc).
P.S.- have been using the service now for 4 months.
