One of the things I used to be able to do is use my Tungsten T and my Sony Ericson phone to dial up my ISP and connect to the internet to get mail, surf, etc. In theory, the 650 should be able to do it directly without having to subscribe to some stupid overpriced (Cingular) data plan. At any rate, I am interested to see if this can be done and how to do it. I suspect that I have had no luck thus far a because of the disabled DUN similar to that of the Sprint version. At any rate, if someone has any advice or such, please let me know. When Cingular figures out that their data plan is about $20 over the market and drops it to a more reasonable amount, I would be happy to subscribe. Thanks in advance.
