It is very easy to get that working:
You just need to use a good Internet browser for your mobile phone. Beware: do NOT use a WAP nor an IMODE (for Mobile phones pages only) Internet browser, but a general Internet browser, such as Opera Mobile.
In my case, I have an average multimedia mobile phone: my old Motorola V300 and I use it to work anywhere I go, just browsing the Internet, as I do at work. I also have an e-mail in it, so it is very useful to keep connected when you go to have a drink with your friends or so, keeping an eye from time to time in your important projects. I use to have a look at my web sites and course servers, and even to enter http://moodle.org.
It is really amazing to have your whole work in a 122 grames (4.3 oz) device that you can control with just one hand, while holding your cold beer in the other one.
