I am not really sure what the price in india would be but I guess you can get a rough estimate by checking what the price in USD is. I'm sure it would be a little above the US selling price
The 3G cost somewhere between 31,000 INR - 35,000 INR. The new 3Gs would definitely cost much more than that, being a better model. It has been predicted that it could cost somewhere around 40 - 45K INR, while the cost of the older models might drop.
iPhone 3GS costs approximately 49000 INR its really worth buying this phone and i'm waiting to get one soon.I got this info from the leading mobile selling site in india. check out in Univercell.in they just mentioned it as aproximate price so it will oscilate around 45000 INR to 50000 INR
