PDANet is free and easy to use and does not require being rooted. Power down phone, remove SIM card, boot up phone, connect to internet via WiFi and then search the Market for PDANet. Once you get it on your phone, you will need to install a program on your computer.
PDANet, works wonders here . I rather use PDANet for the simple reason that AT&T can't detect it connecting to your laptop or desktop, using USB tethering on USB options on the phone will risk being discovered, my personal view.
Thanks, I will give it a try.
I was able to do tethering through Kies yesterday, so I upgraded my firmware. Now Kies can not connect my phone, and I lost that built in tethering... Hope PDANet will work.
After the update, I lost "PC Internet" tethering; however, I could tether through Kies. With Kies, unlike PC Internet, I could not place calls or have someone browsing on my phone while I browsed on my tethered netbook. Installed the free version of "Easy Tether". Now I can do it all. Also, you don't have to root your phone or remove your sim card. Just put the phone in "Flight Mode" and use a wireless connection to download and install the app. The paid version, $10, allows you to connect to secured sites. I have it set to automatically complete the connection anytime I tether the phone via USB to my netbook. Some people tether through Bluetooth; however, as I understand it, Bluetooth will restrict your download speed to a max of 800kb. I normally get 1.5mb to 2.0mb using USB.
