yes you can!!!
The first thing you have to do is set your phone to act as a tether. To do this:
1. Go to START-SETTINGS-SYSTEM-DATA CONNECTION.
2. Choose the second option, which is"As the modem through USB."
3. Connect the cable from your phone to the Mac.
4. Once connected, your phone will recognize that its connected. This can be confirmed when you click on the phone receiver icon then choose "network preferences." You should see Samsung listed there.
5. click on the Samsung option and enter the following:
For Telephone Number enter #777
For Account Name enter your phone
number@vzw3g.com (xxxxxxxxxx@vzw3g.com)
For Password enter vzw
When you now click on the phone icon, you will see the option "Connect SAMSUNG CDMA Technologies"
you should now be connected.
Keep in mind, this is if you have a Verizon wireless account. Also, I pay the additional charge for tethering. If you want to try it, Verizon will give you a free month of tethering. It is a little pricey. $45 for unlimited internet and an additional $15 for tethering. There rational is that, if you're tethering, you are accessing as much bandwidth as the USB access that they sell for $60 a month.
Good luck.
