There are some hidden options which you have to enable via modifying some file.
(see [here](http://www.funkyspacemonkey.com/iphone-os-30-episode-iii-howto-enable-battery-percentage-toggle-settings)
and [here](http://www.funkyspacemonkey.com/iphone-os-30-episode-iihowto-enable-videorecording-interface-iphone-2g3g).)

Enable a feature
================

For this you have to have [ssh-access]({% post_url 2009-04-26-ssh-access %}) enabled!!

1. `ssh` into the iPhone (remember: the `root`-password is **`alpine`**)
1. `cd` to `/System/Library/CoreServices/Springboard.app/`
1. run this command: `plutil -c xml1 M68AP.plist` (this will convert the binary-XML to plaintext)
1. now use `nano`, `mcedit` or `vim` to edit the file
1. find the **capabilites** dictionary right at the top of the file
1. add the following two key/value-pair: 
   {% highlight xml %}
<key>gas-gauge-battery</key>
<true/>
{% endhighlight %}
1. save the file
1. run `plutil -c binary1 M68AP.plist` to convert the file back into binary-XML format
1. logout
1. reboot(=respring) the iPhone


Features Explained
==================

accessibility
-------------

This will add a new settings menu below *General* (right below *International*). It is empty on iPhone 3G.


gas-gauge-battery
-----------------

This will enable a new setting under *General* → *Usage* to enable a percentage field left of the battery icon.


video-camera
------------

This will enable a new photo <=> video switch in the camera interface.

<p><div class="notewarning" markdown="1">
Enabling this feature will make the camera **unusable**! You won't be able to take normal photos with this feature enabled. (as of BETA 5)
</div></p>


voice-control
-------------

This will add a new settings menu below *General* → *International*. It is empty on iPhone 3G.

Anyone tried `nike-ipod` or enabling the `magnetometer` on a 3G? Also what could `green-tea` be?
