Coincidentally... I'm planning on taking my n810 / n82 on a trip to india... in 4 days time! (I'm a little excited)

My plan was to pick up an Airtel pre paid sim with some data so i can blog / check email / upload photos on the move. Ive read Airtel is the best carrier, is this true?

What kind of gprs speeds can i expect? I know there is no 3G to speak of, but is there EDGE? Any advice from anybody in India would be appreciated
