I think you talking about mobile computing after Internet connection made, why?

From your manual:

1. From the Home screen, press MENU, and then tap Settings.
2. Tap Wireless & networks.
3. Select the Mobile network check box to turn on the data connection; clear the
check box to turn off the data connection.

Whenever you connect your phone to a computer using the USB cable, the Connect
to PC screen opens and lets you choose the type of USB connection. (Select disc drive)


Copying files to or from the storage card
You can copy your music, photos, and other files to your phone’s storage card.
1. Connect your phone to your computer using the supplied USB cable.
2. On your computer, the connected phone is recognized as a removable disk.
3. Navigate to the removable disk and open it.
4. Do one of the following:
Copy the files from the computer to the phone’s storage card’s root folder
Copy the files from the phone’s storage card to a folder in your computer.
5. After copying the files, unmount the removable disk (that is, the connected
phone) as required by your computer’s operating system to safely remove your
phone.
