The process is very simple, but you should know it isn't free. This process will cost you $20, but only once.
Here's how it works:
- First, you need to jailbreak your iPhone.
- Second, download the MyWi app from the Cydia store (which you'll find on your jailbroken iPhone). You may have to search for it, but chances are you'll just see it advertised on the Cydia front page. To buy it, you'll need to authorize your account through Google or Facebook and Amazon or Paypal. Once you've purchased MyWi, click the install button in Cydia and it'll install it on your iPhone.
- Finally, launch MyWi application from your iPhone's home screen and click the Wi-Fi button up top (the second button from the left). All you have to do is flip the "WiFi Hotspot" toggle and you're ready to connect any other device via Wi-Fi.
