Emerging mobile phone market

Recently i was looking into some interesting numbers compiled by EEtimes which tells that developing countries currently accounts for more than half of the mobile phone subscriber growth.Interestingly Y-Y growth(2005 to 2006) in India,Pakistan,Bangladesh is 100%.Thats a lightning number.Falling handset prices,Cheap tariffs and rising incomes contributing significantly to these numbers.Its one example that tells how quickly times are changing.I guess logical next step would be broadband but still there are lot of infrastructure and PC penetration issues.But never say never!!
