Yeah now i am able to use the data too, people working in the tata docomo showroom are crazy i guess. I recharged for 48 and now i am able to get data. 1mbps avg in speed test, far better than cdma.
Also i want tried to change the Operator name in Build.prop but still shows USC, its a bit annoying but i can live with that. Is there any specific edit in Build.prop to get the phone to show Tata.?? thanks
