Wi-Fi tethering allows the user to convert their GPRS or 3G internet from their mobile service provider to Wi-Fi signal so that you can connect your laptop, tablet or Smartphone to use the internet.

With Wi-Fi tethering, also known as Wi-Fi Hotspot, you can do away with the data card and convert your iPhone into a Wi-Fi hotspot and connect your laptop or tablet to the device and start using internet on it.



With the iOS4.0 operating system, AT&T started allowing internet tethering on the iPhone. So now, AT&T and Verizon, users can purchase the Wi-Fi tethering plan for your iPhone 4. However, on jailbroken devices, users can use apps like MyWi on Cydia to turn on the Wi-Fi hotspot.

In India, Vodafone and Airtel offer tethering service at an extra cost.

2.      After step 1, you can now tether your iPhone 4 using MyWi, without plugging your device to the ad-hoc device.

However, since the app is battery consuming, it is advisable to put the device on charging while using the app. The MyWi app is available for free usage for only 10 days. Thereafter, you will have to pay $10 to continue using it.
