How does it work

iPhoneModem has two sides: the Modem application on the iPhone and the iPhoneModem helper for the Mac or the PC

On the computer, the helper application creates a new computer-to-computer (or ad-hoc) WiFi network and configures the system preferences to use the iPhone as a proxy.

On the iPhone, the application opens DNS, HTTP, HTTPS and SOCKS proxies and connects to the helper on the computer.

Who are we

iPhoneModem has been developed by Addition, Lda. mainly by Diogo Vitorino and Fábio Bernardo; all graphic and interface design is attributed to Pedro Rufino.
Addition was established on 1998 and has since then been on the mobile applications market with a, now quite old product, for the PalmOS named Addition4Palm.
Addition’s iPhoneModem has the objective of being a beautiful, simple, stable and small footprint application for the iPhone and the Desktop computer that anyone can use on a few seconds.

Frequent Questions

Why isn't it on the AppStore

Because Apple still doesn't approve Internet sharing applications for the iPhone.

Why use the proxy technology?

A proxy is different from a router or a gateway because the latter will send all traffic through the iPhone. A proxy receives a request from a proxy aware application on the computer, analyzes it and creates a new request which it will send to the desired Internet host.

The advantages of using a proxy on this scenario is that outbound traffic is originated on the iPhone and only the traffic from applications you control do it.

Is iPhoneModem secure?

On the mac helper app preferences, you can define a password and change the name of the WiFi network. If you do, communication between the iPhone and the computer is encrypted.

On Windows, you can secure the WiFi network created by the helper app by using windows WiFi/network connection settings.

Since all traffic is proxied, it is much easier to control which information is going through your iPhone's connection.

Why doesn't it work behind the scenes (on background)?

The best way to save battery is not to have a sharing application running.

If you keep a sharing application running, you do create a security risk everytime you connect to an WiFi network.

How much traffic can I use?

iPhoneModem does not limit the amount of traffic but it let's you monitor your total traffic: you can check how many traffic you have generated by clicking the info button on the iPhone. You can also reset it back to zero.

The amount of traffic you can use depends on your agreement with your cell phone provider.

Can't find it on Cydia

Try refreshing and updating cydia. Remember this application requires iPhoneOS >= 2.0.
If that does not work please make sure that the http://apt.modmyi.com/ repository is installed (on Manage>Sources).

Application "X" is not working

Make sure the application supports a SOCKS or HTTP Proxy and see how you can enable it, for example Firefox does not look at the System Preferences and you have to manually configure it (see Firefox Guide).

Ad-hoc networking doesn't close

Sometimes, namely on MacOS Tiger the created WiFi network does not disappear even after you quit iPhoneModem.
You can see that on the Mac WiFi icon when it's looking like a computer. To release the WiFi network you must disconnect the iPhone and Mac from that Wifi network (by default named iphonemodem).
