1.) It would have been better had you written the title something like "where to get Galaxy S in Delhi" instead of just "Galaxy S". No good forum manners I shall say.
2.) Having said that my friend who also stays in New Delhi wanted a galaxy S for herself and it seems that its out of stock so she has booked it.
Though I find it strange that its out of stock. Few months back when I bought it it was lying in almost every other shop!
