Bit dopey here - should I be able to set up my SE W800i on O2 to be able to access the internet on my PDA ?? And if I can, is it likely to cost loads ?
Yes you should beable connect your PDA via your Mobile. As for cost, it depends on usage and what type of contract you have with O2. I use Vodaphone on a monthly contract on which I pay £6 per month for data/text. Bearing in mind that connection speed is dial-up and is SLOWER than dial-up to a home PC/laptop, downloading anything significant in size to your PDA is both slow and costly. I use mainly to view truncated versions of my Emails. £6 per month doesn't go very far if you want to do any browsing. O2 should supply tou with the necessary settings for both your phone and your PDA.
