I've Google'd to find out what those files are and found out that they are those "auto-correct dictionaries". Because I dont need all of them, I deleted all of them, EXCEPT three, English, German and Emoji.
I kept English and German because I use both of them sometimes.
And I kept Emoji because I dont really know what that is so, just in case lol.

Anyway, after deleting those and re-spring'ing my phone, my root partition went from 91MB free to 140MB! That's 49MB on the small partition!

Dont have any problems (as of yet).

Definitely worth deleting if you're not using all 34 language dictionaries! :P

interesting.. nothing bad happened when you reboot?

**jdys_1991** · 09-05-2009, 01:49 PM

I rebooted after I posted my previous post, and NO, NO PROBLEMS AT ALL!!

It's working perfectly. I tried Notes.app to check if the normal english dictionary still works, and guess what, it WORKS!!!

So it's safe to delete, i'd say. But DO make a backup, just in case!

**jdys_1991** · 09-08-2009, 09:35 AM

Ok. Found some more stuff which is safe to delete.
Here is the list:

\Library\Audio\Plug-Ins\HAL\VirtualAudio.plugin
Save to delete all but English (I also kept German).

\private\var\stash\Ringtones.Owzlcu
Save to delete all but Alarm & custom ones (Didnt try deleting all of the stock ones, so left one)

\private\var\stash\Wallpaper.wvSjka
Save to delete all but 101* (Didnt delete all of them, left one)

\System\Library\Carrier Bundles
Save to delete all but O2*, ATT & Unknown (Didnt delete all, depends where you live. For me I just kept AT&T and Unknown just in case)

\System\Library\TextInput
Save to delete all but English (Kept German & Emoji just in case)

\System\Library\PreferenceBundles\CyDeleteSettings .bundle
Save to delete all but English (Kept German)

Just to let you guyz know.

Any noticeable increase on battery life? Just wondering cuz I'm assuming background processes take up some batterly life too. Eliminating some of the daemons, had anyone noticed an increase on battery life on a 3G?

**jdys_1991** · 09-08-2009, 10:53 AM

I can't really say anything about battery life, because I didnt delete any daemons (except the crash report ones), because I messed my phone up before. I just delete files which waste space on my phone, which certainly does make the phone a lot snappier.

Sowi, cant help you with that. :/
Maybe someone else can comment on the battery life.

**i.Annie** · 09-08-2009, 11:12 AM

thanks tho.

I'm at work so I can't try it yet :P i just wanted to know cuz I have only had my phone off the charger for 3 hours and I'm down to 66% when I barely use it (besides right now). I was hoping to find out if anybody has a battery life increase by removing the max amount of daemons possible or at least close to the max. Preferably an input on 3G phones would be nice

**jdys_1991** · 09-08-2009, 12:06 PM

Well I personally noticed that using the internet a lot, sux for my 3G.
If I just play games, watch movies or listen to music, it's not that bad.
But anyway, I can use my phone for probably like 36 hours before I would need a recharge. But that's when I really supress my self. :P

Dont know what it does, but it's part of the SystemConfiguration framework.

jdys,did it make your iDevice faster?Also any clue as to which one of these are actually included in the ipod touch?Also,will this have any effects to how it runs?Also,are permission changes necassary?If so,what are the EXACT terminal commands? (all of the needed ones)

Hey lol
Well I would say that I may not have a huge increase in the amount of RAM free (probably only gain 2-3MB), but it certainly has made the phone snappier! What I mean with this is that by removing those crappy language files and unnessecery file of the phone, it makes it run smoother, and a lot more stable!
I havent seen any side effects (yet lol), so I would say it's safe to delete the language files.
However I messed my phone up once by deleting a daemon which I shouldnt have, and it made my GPS not working anymore. So this time, I left my fingers from deleting too many daemons.

No, you dont need to change any permissions.
But make sure you keep a backup of all the files you delete, just in case.

Hope this helps.

@Melech518 - I did it 100% right

I got an extra 17mb on my 3GS, and it got rid of the animation lag when opening/closing some apps such as Cydia.

You are right about the cydia apps, on a fresh restore i get around 180mb free but with my cydia apps i get around 160mb to 170mb at the most free...

Main Cydia Apps Installed
Cydia (1.0.3030-62)
FiveIRows (No Gui)
FontSwap
Hunspell
iFile
inspell
Music Controls
PhotoShare Web
PushMod
ReflectiveDock
Safari Download Manager
SBSettings
Sleep To Lock
StatusNotifier 3.0
WeatherIcon
WinterBoard (No Lockscreen Themes)
YourTube
3G Unrestrictor

If anyone knows which of this is more memory heavy might be good to know lol

@Carlbgc - how much ram you got free on average on your 3GS and what deamons did you remove? Also did you remove language packs?

anything that uses mobile substratee eats up your ram. It looks like you have a lot of things that use obile substrate. Type in "mobile substrate" in cydia then hit remove or whatever. Dont confirm the action though, just see what apps you have that use it. Then from there, you can delete whatever apps you dont need.

**Ro-K** · 09-10-2009, 01:36 AM

which is better to delete language packs or remove daemons? cuz i deleted LP's and idk maybe reading all these posts about making phone snappier brain washed me and i think its a lil faster...

i have a 8gb 3g 3.0

**angiepangie** · 09-10-2009, 01:37 AM

do both.
That's what I did.

**unsleepable** · 09-12-2009, 04:22 PM

Just did these along with the language pack removal and see no noticeable improvements. Free memory maxes out at around 45mb, with about 34mb free after fresh reboot. No marked improvements in reboot times.

I'm not complaining, I guess i'm glad everything still works after the operations. Wish I had a 3gs so I wouldnt have to mess around with these type of things.

**StealthBravo** · 09-12-2009, 04:28 PM

Mine is so quick after this

**angiepangie** · 09-12-2009, 05:41 PM

Ughh... I forgot about this.. I'm not doing the language packs & this again :/
Oh well my phone's fast enough even without it now

**HTKnightq** · 09-12-2009, 07:56 PM

Just to tell you all,permissions DO NOT need to be changed.I was confused as to what to do with that for a while,then a friend of mine who did this without changing permissions told me it was fine.I tried it out and no problems so far.It's been two days.Anyways,I'm still deleting language packs,and removing over-written theme images,but with the *very* few launch daemons I've deleted,I've noticed a HUGE speed increase.Tap Tap Classic no longer lags,and maybe it does just the littlest bit on Through The Fire And Flames which is actually a pretty fast song.After a fresh respring,I get around 35mb,and I've only done the default apps for language packs.Theres still a ton to delete,as well as those for the new method jdys figured out.When I free up memory with SBSettings I get roughly 45 and with a second memory clear up I've gotten to 52ish but I believe I got up to 54 once.

**phreakwenci** · 09-13-2009, 06:01 PM

So wait.. Where's a complete list of everything that's safe to get rid of, and how to do it safely?
