Right, I looked into that and UP.browser is a particular kind of browser. Not all mobiles will have it. It looks like there is a lot of variation out there, so I will just look through my server logs for clients that have unusual browser types and add them in. Now, maybe you can answer another question: Is there any way to detect the phone number of the browser, or anything else that would let me send a WAP push back to the same browser?
