I recently upgraded my iPhone 3G to 3.1.2 and JailBroke it. So I decided to try the experiments to speed up the iPhone by removing language packs and disabling launch daemons. The iPhone seems more snappier since doing this, read more to see the full story.
This tutorial is for Windows only, you will need to download i-FunBox.
I went through all the following folders and removed all lproj folders except for English.lproj or en.lproj. I also deleted DemoApp.app, FieldTest.app, Maps.app, Stocks.app, VoiceMemos.app and Weather.app from /Applications/.
– Can delete all but English or your language.
– Can delete any of them.
– Can delete all except 101*.
– Can delete all but English or your language.
– Can delete all except en.lprog / English.lproj.
– Foundation.framework (keep en.lproj)
Now what we can do is disable the Launch Daemons at startup. Navigate to /System/Library/LaunchDaemons/
