Fix the keypad speed

A classic problem with the Nokia 8110 4G is the too-strange typing speed. Here is the solution to fix typing to a more human level.

1. Extract the system application that manages the keyboard:

adb pull /system/b2g/webapps/keyboard.gaiamobile.org/application.zip

2. extract the application.zip, open the /js/keypad.js file and change the values in this line

Keypad.prototype.LONGPRESS_INTERVAL=1000;Keypad.prototype.IDLE_INTERVAL=1000;

in this way

Keypad.prototype.LONGPRESS_INTERVAL=500;Keypad.prototype.IDLE_INTERVAL=400;

3. update the app using webide. Now all works as should, without reboot the phone and without changes on the system partition. Enjoy your writing now! ;)
