Windows Mobile 2003 demoted

My Windows Mobile 2003 PDA has been demoted dispite finding a better web browser in the form of Opera (go to m.opera.com on your mobile). I still use it for a sync version of my personal email plus all my contacts on Outlook 2002 (SP3) running on Windows 7. I had been carrying around three mobiles which have now merged into two. I have moved from pay-as-you-go to Vodafone pay monthly for pesonal and business mobile. A contract I have through Carphone Warehouse for txt and data. This means I can check emails. The phone the Nokia E5 which I am very impressed with.
