Compatibility: iPhoneModem has been tested on all iPhoneOS and iOS devices since version 2.0 (September 2008)

Sharing: the internet connection can be used by several devices.

Security: you can use WiFi security to protect the shared internet connection.

Speed: full 7.2 Mbps 3.5G speeds can be achieved (with optimal network reception).

Usage: iPhoneModem and the helper app on the computer provide a simple one-click solution to internet sharing.

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.


How to Install

1. Jailbreak the iPhone (if you haven't already)

2. On the iPhone use "Cydia" to install iPhoneModem - it's filed on the Networking category. After installing a new App named "Modem" should be available on the iPhone.

3. Download and install the helper application.

How to Use it

After installing iPhoneModem on the phone and on the computer, open the iPhoneModem on the computer and click "connect".

A new WiFi network is created by the computer and, on the iPhone you should select it and open the "Modem" application. When connected everything should be automatically configured.
