Enable a feature

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

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

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)
