P/S: the photo was made in Year 2010.
I took a quick look at the brochure. IPhone 3GS will be free of charge when you sign up RM50 monthly plan with 24 months contract.
I tried to find the plan on maxis website but it was removed. I heard that the response is overwhelming and iPhone 3GS units are currently out of stock. Maxis customer service said that there will be replenishment in the future and they are reviewing the plan for better package.
