The key to 3G: cheap voice calls?

According to FT.com, Hutchison 3G plans to build a subscriber base for its new 3G services across Europe by undercutting its 2G rivals on the price of voice calls. That makes sense: while the analysts scramble around looking for the "killer" 3G service, the answer continues to stare them in the face: it's voice calls. What is not yet clear is exactly how much the first 3G phones will cost to the consumer - the FT says they will cost $750 to make. Consumers will not pay that much, so it's pretty irrelevant worrying about what the cost of calls will be if the subscribers are being put off by the initial price of the kit, or a high monthly subscription.
