Always Take The Tether With You: App Lets You Use iPhone As Wireless Modem

Wouldn’t it be great if, somehow, you could use your iPhone as a kind of wireless modem for your laptop and connect to 3G coverage when you’ve got no Wi-Fi access?

Well hold on to your hats, because one clever techy fella has created an app that does just that – though you’ll have to hurry if you want to get your hands on it.

The £1.49 app is advertised as a tool which enables you to read or play media files on the go, but if you know what you’re doing, it can act as a ‘tether’ between your laptop and your mobile network.

QuasiDisk’s tethering ability is hidden behind its main selling point as a file manager, but in a video to mark the app’s latest update, developer Chris Simpson shows how to use the hidden function.

In the video, he walks through the process, which basically involves creating an ad hoc network on your laptop before starting QuasiDisk’s FTP server on port 5100 and writing down the full server address. Then you can connect your laptop to the FTP server via proxy. If none of that made any sense, there are plenty of video walkthroughs explaining it.

Apps which offer free tethering are usually removed from the App Store very quickly, so you might want o get it downloaded fast, before Apple’s heavies move in and boot it out.
