Aircel is currently offering probably the cheapest deal on the iPhone in the Indian market.
They are selling iPhone 3GS for Rs. 10,000 with a small catch. You have to pay an advance rental of Rs. 3000 which gets you 2GB data at 3G speeds (and unlimited on slower speeds after that) for a period of 12 months.
This is a postpaid plan only offer.
For users in regions where Aircel does not have 3G networks, the package comes loaded with 1000 minutes of local and STD calls in addition to 2500 local and national texts with unlimited 2G data for 6 months.
Overall, this is a great offer for anyone looking to buy this edition of iPhone for cheap.
