If jailbreaking your iPhone 4 is not enough and you wish to squeeze that little small extra performance off it, then proceed as follows...


1. Login (SSH) into your iPhone.

  • SSH to your iPhone with your favourite SSH client.


2. Create a New "backup dir" to which to move some useless daemons.

Why move? Because this way you'll never accuse me of telling you to delete iPhone System files.


mkdir Sys-Lib-LaunchDaemons-bck


3. Go to the (real) location of those useless daemons.

You'll need to first locate those files.


cd /System/Library/LaunchDaemons


4. Relocate those daemons' files out of your iPhone RAM!

Now move the files listed below From "/System/Library/LaunchDaemons" To "/var/root/Sys-Lib-LaunchDaemons-bck" ("mv" command follows, just copy/paste).

-rw-r--r-- 1 root wheel 540 Oct 20  2012 com.apple.AOSNotification.plist
-rw-r--r-- 1 root wheel 162 Oct 20  2012 com.apple.CrashHousekeeping.plist
-rw-r--r-- 1 root wheel 207 Oct 20  2012 com.apple.DumpBasebandCrash.plist
-rw-r--r-- 1 root wheel 142 Oct 20  2012 com.apple.DumpPanic.plist
-rw-r--r-- 1 root wheel 333 Oct 20  2012 com.apple.ReportCrash.DirectoryService.plist
-rw-r--r-- 1 root wheel 303 Oct 20  2012 com.apple.ReportCrash.Jetsam.plist
-rw-r--r-- 1 root wheel 306 Oct 20  2012 com.apple.ReportCrash.SafetyNet.plist
-rw-r--r-- 1 root wheel 330 Oct 20  2012 com.apple.ReportCrash.SimulateCrash.plist
-rw-r--r-- 1 root wheel 306 Oct 20  2012 com.apple.ReportCrash.StackShot.plist
-rw-r--r-- 1 root wheel 300 Oct 20  2012 com.apple.ReportCrash.plist
-rw-r--r-- 1 root wheel 230 Oct 20  2012 com.apple.mobile.profile_janitor.plist
-rw-r--r-- 1 root wheel 403 Oct 20  2012 com.apple.powerlog.plist

  • Type the following "mv" terminal command to move the above files:

mv com.apple.AOSNotification.plist com.apple.CrashHousekeeping.plist com.apple.DumpBasebandCrash.plist com.apple.DumpPanic.plist com.apple.ReportCrash.DirectoryService.plist com.apple.ReportCrash.Jetsam.plist com.apple.ReportCrash.SafetyNet.plist com.apple.ReportCrash.SimulateCrash.plist com.apple.ReportCrash.StackShot.plist com.apple.ReportCrash.plist com.apple.mobile.profile_janitor.plist com.apple.powerlog.plist /var/root/Sys-Lib-LaunchDaemons-bck


5. Reboot your iPhone.

On the terminal, type:


After you reboot your iPhone, the above daemons won't be loaded into RAM anymore.



If you want your GUI to "go faster", install "Accelerate" (from the Cydia repos).

Accelerate will speedup your iPhone GUI transition speed for free. Also, nitrous is worth a mention (though it costs 0.9c).
