Got it going with the "Connect To" under the start menu, after I learned ATT'c connection info. In the "dial up phone number" box, you put *99***1# and in the "Connection name" box you put "AT&T" (without the quotes of course). Then you just check the little box that says "Allow all users to use this connection" and hit "Connect" and thats it. It takes about 30 seconds to connect but then you are browsing. The funny thing is, according to speedtest the connection speed on my phone is twice what it is on my DSL landline.
However, in real life, the phone speed seems almost as fast as the DSL. But not quite. It's definitely far faster than any other "Dial up" connection that I have ever used. My speedtest for my DSL is 1.31mbps, and for the phone it's 2.86. Now, one thing you should know (in case anyone here might attempt this) is that I have a samsung solstice, and I was told that it is a little different and you might have to use other numbers than the *99***1# to connect, on other phones. That, and you have a 5Gb download limit before they ass rape you on your bill.
Also before you do the initial setup, you are going to need to install the "Samsung PC studio" program. It installs all the drivers that make windows see the phone as a modem it can use. And you will need to have the unlimited data plan (an extra $10 a month) to even be able to do this at all. Otherwise the network blocks you or something.
