My wife ha been having problems trying to use "Internert tethering" to connect her laptop to the internet via her iphone 3gs..?

Be very very careful when you use tethering from a cell phone. If tethering is not included as part of your phone's data plan, you could end up with a bill in the thousands. I've seen it happen dozens of times when I worked for a cell phone company.

1. Enable the tethering option on your carrier's data plan. Many carriers charge extra for this service, and prices vary, so contact your carrier for specific details.

2. Make sure that you have an iPhone 3G or later. Only these generations of iPhones support tethering.

3. On your iPhone, tap Settings, General, Network.

4. Tap the Personal Hotspot option.

5. Tap the Wi-Fi Password option. This will enable you to prevent unauthorized devices from connecting.

6. Type your desired password and tap Done.

7. Slide the Personal Hotspot option from OFF to ON to enable Internet sharing. The phone will create a Wi-Fi network with the same name as your iPhone device name (John's iPhone, for example).

To connect your other devices to the phone's Internet connection, add them to the Wi-Fi network that the phone created, using the same process you would for any other Wi-Fi network. You'll have to follow different steps for Windows 7 devices and for Mac OS X, as follows.

Windows 7

1. Click the wireless network icon in the system tray to bring up the list of nearby wireless networks.

2. A network with the same name as your iPhone will appear. Select this network, and click Connect.

3. Type the password you chose for the network, and press Return.

HI, My IPhone is a 3G , does not have Personal Hot Spot option but does have Internet tethering is this the same?
