It is interesting that cell phone providers are encouraging their customers to use them to replace their landlines, but they have no toll free product.  There is no technical problem terminating toll free on a cell phone, but I haven’t been able to identify any cell phone provider with a toll free service.  As far as I know the cell phone companies already have contracts with landline companies and landline companies have reasonable easy ways to feed billing information, why would the cell companies not offer a service?
