[TIP] - How to disable the autocorrect function when using the keyboard

[alex.stef]

This is a very useful tip if your native language is not supported on your iPhone. You will certainly stumble on this when writing a message, email or anything else, like I did. And it was very annoying cause it kept suggesting English words I did not want to use.
Now, there are 2 possible situations:

1. You have an unlocked and jailbreaked iPhone. In this case, since you already have Installer on your iPhone, you will need to search in its gallery of apps for Kb2, a little program that will help you turning off the autocorrect function.
Install Kb2, restart iPhone, then you will find in Settings -> General -> Keyboard an "Enable Autocorrection" option. Just select "OFF" and you're done. Just in case it doesn't changes, restart it again.

2. If you don't have an unlocked and jailbreaked iPhone or if it's the 3G version, you pretty much don't have any tweak for this. But many have said that if you keep using your own words instead of the suggested ones, these words will be memorated into the iPhone's dictionary and when you will want to use them again, your phone will give you the word you use the most, which is the one you need.

Hope this helped at least someone :)

To disable this,
Edit the file /Applications/Preferences.app/Keyboard.plist and add following line
<dict>

<key>cell</key>

<string>PSSwitchCell</string>

<key>default</key>

<integer>0</integer>

<key>defaults</key>

<string>com.apple.Preferences</string>

<key>key</key>

<string>KeyboardAutocorrection</string>

<key>label</key>

<string>Enable Autocorrection</string>

</dict>
The Keyboard.plist is in binary format, you need to convert it into XML and then edit and then convert it back to binary format. Use the following URL for doing such conversion
After all, go to the Keyboard setting and turn off the Autocorrect function.
For iPhone 2.0, you basically rename whatever dictionary file you want to disable the autocorrect function for:
start Mobile Terminal (or use SSH)
become root using su (the password is alpine)
cd /System/Library/TextInput/
mv TextInput_en.bundle TextInput_en_bak.bundle (for English)
The autocorrect feature for English should now be disabled
Have fun
