Installing Java on an iPhone used to be an
impossibility. Apple's Steve Jobs has even
said it is not useful enough to integrate
into the iPhone. But now with endless
possibilities in the jailbreaking/homebrew
scene, Java on the iPhone is a reality. All
you need to have is a jailbroken iPhone/
iPod Touch and Cydia installed on your
device. Cydia is like the Apple AppStore, but
with useful applications. Having Java on
your device will allow you to run the many
Java applications that are available on the
PC.

Turn on your jailbroken iPhone or iPod
Touch (see Resources section). Make
sure you are on either a 3G network or
on a Wi-Fi connection. To do this, press
"Settings" and then "Wi-Fi" to find your
closest network. Enter in the security
passcode, and you will be connected to a
much faster network than even the 3G
speeds of the iPhone.

Press the "Cydia" application on your
home screen. Cydia is an app store for
the "Open iPhone" and gives you more
customization options and apps that
Apple will not allow on the AppStore.

Wait as Cydia loads and downloads all of
its latest packages. Press the "Search"
button on the lower right side and type
in the word "Java." A few results will
come up, with "iPhone/Java" being the
top result. Press on that app.

Press "Install" on the top right corner of
the next screen, and the app will be
downloaded and installed. You will now
have access to the many different Java-
based tools.

Na only 3g or wifi fit work?
