Reverse Wi-Fi Tethering for Xperia X10

This is pretty simple and you just need to install this App on your Laptop and it would simply turn your Laptop into a Portable Wi-Fi Hotspot and it’s not like any Ad-Hoc Connection as it shows up like a real Access Point.
The App is Connectify. Connectify is a free Windows 7 application that turns your laptop into a real Wi-Fi hotspot to share the Internet with friends, co-workers, and mobile devices. Connectify allows you to take any Internet connection and share it wirelessly with no additional hardware, wires, plugs, or chargers.
You can then easily connect any number of WiFi enabled devices to your personal network including laptops, phones, gaming systems, and more. WiFi enabled devices can see and join your Connectify hotspot just like any other WiFi access point and are kept safe and secure by rock solid WPA2 .

This is not a simple Ad-hoc connection, its a full blown Access Point allowing you to host or repeat a network and receive an Internet connection at the same time, using one Wi-Fi card.
