LockerGnome reader Greg asks, “Can I share a tethered Web connection from the iPhone with multiple computers?”

Before I begin to suggest a method for accomplishing what I believe Greg is asking for, I’d like to state up front that Greg lives outside of the U.S. and I’m giving this advice with the assumption that he has an account with his carrier that allows for this kind of use. There are a few methods to go about accomplishing a shared Internet connection through the iPhone or iPad with other devices in your home.

First, there is a built-in feature on current iOS versions that turn your iPhone in to a personal hotspot. Using this method, you can connect up to five devices to your iPhone and share your data connection with them. Keep in mind, though, that many carriers and plans have caps on the amount of data you can send and/or receive. This limit can easily be hit using a notebook or desktop as they are written with a data frugal mobile device in mind.

Another method of accomplishing this is through an app available for jailbroken iPhones called MyWi by a company named Intelliborn. MyWi is a tethering app that turns your iDevice into a portable Wi-Fi hotspot. This connection is both secure and can be customized to fit your needs. For example, you can set the Wi-Fi channel to avoid conflicts with other networks.

It will require you to jailbreak your iPhone, which may or may not be allowed by your local laws and regulations, so please check prior to taking this action. Jailbreaking is not recommended for anyone who isn’t absolutely comfortable with the idea of possibly voiding their warranty and “bricking” their phone. “Bricking” is a term used to describe a phone that is inoperable due to corrupted or otherwise dysfunctional software. If you are okay with the risks involved, Intelliborn has a step-by-step guide to enabling your iDevice for MyWi installation here.
