					iPhone as a Wireless Laptop Modem

I travel a lot. And if you’re a geek like me, you can’t go a full day sans internet access
without experiencing some severe withdrawal symptoms. Luckily, my iPhone, with all its
WiFi and 3G goodness, has been instrumental in feeding my addiction while on the road.
But though Apple’s smartphone provides the best mobile browsing experience out there,
the small screen and touch controls still don’t compare to the pixel real estate and tactile
qwerty speed of a laptop. Not to mention such luxuries as Flash compatibility, page
caching, and tabbed browsing.

So the next time you’re stranded without an open WiFi network (but your 3G signal is
going strong), you’ll be glad you installed Addition’s iPhoneModem 2 (free to try, full
license is $9.99). Unfortunately, Apple has apparently deemed the app to be in conflict
with its App Store Terms and Conditions, so it is only available for jailbroken phones via
Cydia. Here’s a quick guide:

1) Jailbreak your iPhone.

Download and install QuickPwn, an easy-to-use jailbreaking application for Windows
and Mac (the latest version works with iPhone OS 2.2.1). Run the software and follow
the onscreen instruction very carefully!

2) Install iPhoneModem by Addition.

QuickPwn installs an app on your phone called Cydia, which is essentially the App Store
for apps that were rejected from the official App Store (or, for whatever reason, the
developer chose not to release through Apple). Run Cydia, search for iPhoneModem by
Addition and install it. Keep in mind you can only delete Cydia installed apps via Cydia’s
Manage-Sources function. Now download and install the helper app on your laptop and
you’re almost ready to go.

3)Set up the network.

Run the helper app and hit Connect. The helper app sets up an ad hoc wireless network
that can be accessed via iPhone. The default network it creates is called “iPhoneModem”
and does not have a password (you can change this in the Preferences of the helper app).
Now open up your iPhone’s Settings and tap WiFi. Make sure WiFi is turned on and
select the network “iPhoneModem” (or whatever you called it). Type the password if you
assigned one. Open up the Modem iPhone app and everything else will configure
automatically. After a few moments the helper app and the iPhone app will confirm that a
connection has been established and you can browse away with all the comforts of your

While 3G seems plenty fast on a phone, it feels a little slow on a laptop. Also, most major
web browsers work but not all are supported. In addition, a lot of other internet
applications aren’t supported, but for all intents and purposes, you should be able to
browse just fine.

*Note: If you haven’t already discovered, jailbreaking your iPhone opens up a world of
possibilities, including themes and apps that aren’t allowed in the App Store. While it
technically voids the warranty, you can easily return your device to its original state with
the “Restore” feature in iTunes, wiping all traces of the jailbreak hack.
