You can get mWebPlayer here
http://www.getjar.com/products/7507/mWebPlayerYou can also try other Java based web radio players.
Connecting to PC. Start Motorola PhoneTools. Connect with Bluetooth or USB (no difference in Internet speed). Click Connect Internet. Select your operator. If it is not there then select other. (I used to have older version of MPT and my carrier was not in the list. I just typed the connection name and APN: internet. Left other fields as they were.)
New network connection is created. You might want to have connection shortcut on your desktop. Just make a right click on your connection and click Create Shortcut on Desktop in Internet Connections window.
Good thing about the shotcut is that it won't launch the MPT, but simply connects with to mobile Internet.
So after the doubleclick on the connection icon, your phone starts to act as modem and transfers GPRS connection into your PC. The Internet speed is slow, but it's there. You can use MSN, browse web, lisen low bitrate radio, manage your e-mail etc.
Be sure to check your data plan, because GPRS usually costs. My carrer has day tickets (I pay a little money and I can use unlimited amount of megabaits for 12 hours), there are also unlimited usage with monthly fee. Without day ticket I pay per megabait and it is quite expencive.
