I have a motorolla v3m red from US Cellular and need to download some music using the USB cable but can not seem to be able to. Also how do you connect to the web to enter a URL?

To download it to your computer you'll need the data cable (which you have) and Motorola Phone Tools.
Here's some info about Motorola Phone Tools:

Here's where you can buy it pretty cheap:

As for browsing the web you'll have to download the web browser application from EasyEdge.

You'll need a program such as Motorola Phone Tools
