What a crazy world we live in. Two of my friends are currently on Orange contracts and they both want new Treo's. If they want to retain their old number they will have to pay £350 for a new phone. However, Orange are actively encouraging them to become 'new' customers with a different number by giving away phone for free or at a much subsidised price (I paid £59). Meanwhile other companies eg Tesco are proclaiming the use of loyalty cards! See here
