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 an Internet gateway and proxy.

On the iPhone, the application opens a routing engine, DHCP, 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.

Frequent Questions

Updating iPhoneModem

To update iPhoneModem from previous versions to 3.1:
a) on the iPhone, use cydia and update
b) on the computer, REMOVE any previous versions, download and install the helper app

For all registered users of previous versions the registration codes will still work. The upgrade is free.

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.

Another distinctive feature of iPhoneModem is that, by design, it's not always on: you control when you want to have it open and can easily monitor the network usage.

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).
