Acelerar Iphone 3G con IOS4

Acelerar Iphone 3G con IOS4

bueno gente, navegando por internet me encontre con este tutorial de como acelerar un poco nuestro iphone 3G con iOS4.....

asi que aqui les va:


lo primero que tenemos que hacer es acceder al sistema de archivos del iPhone, bien por SSH y un cliente FTP o por USB y alguna aplicacion como iPhone Explorer o similar. El primer paso es sencillo y, una vez hecho, ya se nota bastante mas soltura al moverse por el Springboard. Se trata de eliminar las sombras que “proyectan” los iconos sobre el fondo de pantalla y el dock. Para ello hay que navegar a la ruta /System/Library/CoreServices/SpringBoard.app/ y renombrar o borrar los siguientes archivos:

.
La segunda parte es un poco mas delicada pero no hay problemas si se cumplen las instrucciones. Se trata de quitar un buen puñado de los mas de 60 procesos activos que consumen memoria y recursos del iPhone. Te adelanto que la descripcion de los procesos en la lista que voy a adjuntar esta en ingles. De todas formas, siempre puedes quitar los que estan en la seccion de PROCESOS SEGUROS y no enredar con los otros. Si no estas seguro de la funcion de algun proceso, mejor dejalo como esta por si acaso.
.
Primero ve a /System/Library. Busca la carpeta LaunchDaemons y copiala al escritorio del ordenador. Renombra la carpeta original (en tu iPhone) para mantenerla como copia de seguridad. Elimina los procesos que no te interesen de la carpeta que has copiado al escritorio simplemente borrando los ficheros .plist correspondientes. Cuando hayas acabado, copia la carpeta de tu escritorio de nuevo a donde estaba en el telefono. Asegurate de que no sobrescribes la carpeta original y de que la carpeta que estas copiando tiene los permisos 755. Si los permisos no estan correctamente el iPhone no podra arrancar cuando lo reinicies. Avisado quedas.
.
La lista de procesos es la siguiente:

PROCESOS SEGUROS
Pueden quitarse sin efectos negativos por cualquier usuario
.
•com.apple.DumpPanic.plist – Dumps crashes for evaluation by Apple.
•com.apple.ReportCrash.(Different Things).plist – There are 5 of these daemons, and they collect data about what caused a crash, what programs were running at the time, etc.
•com.apple.DumpBasebandCrash.plist – Dumps baseband crashes, which shouldn’t happen during normal use. iPod touch users don’t even have a baseband.
•com.apple.CrashHouseKeeping.plist – Also deals with crashes.
•com.apple.aslmanager.plist – This daemon manages system logs.
•com.apple.syslogd.plist – Logs system events.
•com.apple.powerlog.plist – This is used to monitor any incompatibilities with 3rd party chargers.
•com.apple.stackshot.server.plist – This daemon’s function is currently unknown, but removing it has no adverse effects on one’s device. Some more information can be found Source), but I don’t know what that means, exactly. Removing this daemon has had no adverse effects on my device.
•com.apple.chud.chum.plist – This daemon is thought to relate to Apple’s CHUD (Computer Hardware Understanding Developer) tools. Removing this daemon will have no adverse effects on your device, unless you are a developer.
•com.apple.chud.pilotfish.plist – This daemon is also thought to relate to Apple’s CHUD tools. Removing this daemon will have no adverse effects on your device, unless you are a developer.
•com.apple.psctl.plist – No definitive information about this daemon is currently available, but it’s believed that it deals with connecting external storage devices, possibly a feature coming in new iDevices. It doesn’t do anything for now, though, so feel free to delete it. (Source)
•com.apple.apsd.tcpdump.en0.plist – Logs push notification errors.
•com.apple.apsd.tcpdump.pdp_ip0.plist – Also believed to log push notification errors.
.
PROCESOS CONDICIONALES
Al quitarse, desactivan funciones que puede que no necesites
.
•com.apple.searchd.plist – Disables Spotlight search if removed. The Spotlight page will still be there, but nothing will show up when you start typing. Disable this daemon if you don’t use Spotlight.
•com.apple.AddressBook.plist – If removed, Contacts in the Phone application will load slightly slower. Disable this if you don’t care about that.
•com.apple.accessoryd.plist – If removed, disables accessories like FM radio transmitters, iPhone docks, and AV cables. Accessories will be able to charge your device, but that is all they will be able to do. Remove this if you don’t use any of these accessories.
•com.apple.apsd.plist – If removed, Push Notifications will no longer work. Disable this if you don’t use Push Notifications.
•com.apple.iapd.plist – Functions like com.apple.accessoryd.plist (Source). My personal guess is that it deals with accessories that also come with companion apps, but don’t hold me to that.
•com.apple.dataaccess.dataaccessd.plist – If removed, contacts will no longer sync via Exchange or Google Sync. Disable this if you don’t use those services.
•com.apple.datamigrator.plist – Used to transfer contacts from SIM card to phone. iPod touch users can delete this.
•com.apple.racoon.plist – Used for Virtual Private Networks. Disable this daemon if you do not use any VPNs.
•com.apple.MobileInternetSharing.plist – Used for Internet Tethering. Disable this if you have an iPod touch or if you aren’t interested in tethering.
•com.apple.AOSNotification.plist – This daemon deals with MobileMe syncing. If you do not use the MobileMe service, you can disable this.
•com.apple.AdminLite.plist – This daemon tries to return control of your device to you if it thinks that you are waiting for a lengthly process to respond. It does this by force-quitting the process, so if you’re tired of your apps crashing and you would rather wait a few seconds for them to finish what they’re doing, disable this daemon.
•com.apple.graphicsservices.sample.plist – Thought to have something to do with displaying album artwork. I’ve deleted it on my iPod and everything still works fine, but some people have encountered problems.
•com.apple.UIKit.pasteboardd.plist – I believe that this daemon deals with copy/paste. If you don’t find yourself using copy/paste, you can disable this daemon.
•com.apple.mobile.obliteration.plist – This daemon wipes the data partition of your device. (Source) This will be used if you remotely wipe your phone via Exchange, or if you use Settings > General > Reset, or if you set your device to wipe itself after a certain number of failed passcode entries. If you don’t use these features, you can delete this daemon.
•com.apple.scrod.plist – This daemon deals with Voice Control. If you don’t use Voice Control, you can delete this daemon.
.
PROCESOS DESCONOCIDOS
No se sabe para que sirven. Procede con cautela
.
•com.apple.daily.plist – Nothing is currently known about this daemon, except that it is programmed to perform a certain function once a day. Removing this daemon has had no adverse effects on my device.
•com.apple.iqagent.plist – This daemon’s function is currently unknown, but removing it has had no adverse effects on my device.
•com.apple.mobile.profile_janitor.plist – This daemon’s function is currently unknown, but removing it has had no adverse effects on my device.
.
PROCESOS PARA DISPOSITIVOS ESPECIFICOS
Estos procesos tienen diferentes funciones segun el dispositivo
.
•com.apple.CommCenter.plist – Deals with making and receiving phone calls. iPod touch users (confirmed on the first-gen, assumed on all the others) can delete this daemon with no adverse effects. iPhone users should not delete this daemon under any circumstances.
•com.apple.awd_ice2.plist – Apparently only affects the iPhone 3G and 3GS. It’s not known what its function is on those devices, however, so remove this daemon at your own risk.
•com.apple.awd_ice3.plist – Apparently only affects the as-yet unreleased iPhone 4G. Anyone not using top-secret prototype Apple tech can delete this daemon.
•com.apple.aggregated.plist – It is believed that this performs some function related to Audio-In. If you have an iPod touch and do not intend to use Audio-In, disable this. iPhone users should leave this alone.
.
***NO TOCAR***
Estos procesos son necesarios para el funcionamiento del dispositivo

.
•com.apple.fairplayd.plist – This checks the DRM on your legitimately-acquired music and apps.
•com.apple.installd.plist – Deals with app installation.
•com.apple.BTServer.plist – If this daemon is disabled, your device will become extremely slow and unresponsive.
•com.apple.configd+pm.plist – Deals with system configuration.
•com.apple.configd-pm.plist – Also deals with system configuration.
•com.apple.gmmd.plist – A debugging service for your device.
•com.apple.mDNSResponder.plist – DNS. Disable this, and your Internet is completely gone.
•com.apple.mDNSResponderHelper.plist – Also deals with DNS.
•com.apple.locationd.plist – Deals with GPS and location.
•com.apple.mediaserverd.plist – Plays your music and videos.
•com.apple.usbptpd.plist – Allows your device to connect to your computer and charge.
•com.apple.mtmergeprops.plist – Appears to have something to do with the touchscreen. After I deleted this daemon, my screen was unresponsive. This is why you make backups!
•com.apple.SCHelper-embedded.plist – Appears to be a part of the SystemConfiguration framework (Source), so I don’t recommend deleting it. If some brave soul wants to try it, go ahead and report back.
•com.apple.SpringBoard.plist – This daemon ensures that SpringBoard launches when you turn your device on. Without this daemon, SpringBoard will not launch. Also, this daemon ensures that you are able to respring your device. If you disable this daemon and attempt to respring, the SpringBoard process will be killed but will not start again.
•com.apple.mobile.lockbot.plist – This daemon’s function is currently unknown, but several users have removed it (based on my advice; sorry about that, guys!) and have had to restore as a result. However, I think it’s worth noting that I have removed this daemon on my first-gen iPod touch and have encountered no problems. For the time being, however, leave this daemon alone.
•com.apple.mobile.Lockdown.plist – Deals with SIM and network authorization. iPod touch users, even though this daemon seems like it deals with iPhone-only operations, have still had to restore after deleting this daemon. I have removed this daemon on my first-gen iPod touch and have encountered no problems, but apparently I’m the only one who has been this lucky.
•com.apple.itdbprep.plist – Based on the name, this has something to do with syncing music to your device.

.

PROCESOS DEL JAILBREAK
Son procesos instalados por aplicaciones del jailbreak

.

•com.apple.dynamic_pager.plist – This is what drives virtual memory (VM) mods. Delete this daemon only if you want to uninstall any VM hacks you have on your device.
•com.bigboss.sbsettingsd.plist – Related to SBSettings. I would suggest leaving it alone.
•com.imalc.insomnia.plist – Used to keep Insomnia running through resprings and reboots. If you don’t want it to do that, disable this.
•com.mxweas.MxT2d.plist – The daemon that allows MxTube to download videos in the background. If disabled, the application will need to be reinstalled; however, if you don’t use MxTube and are too lazy to uninstall it, you can disable this daemon.
•com.saurik.Cydia.Startup.plist – It’s believed that this daemon deals with the AutoInstall trick for installing .deb files. If you don’t know what that is and you don’t use it, you can disable this daemon.
•com.saltinbas.free.mem.plist – This daemon is part of the Repeat Memory Free hack that’s been floating around lately. Disable this if you no longer want your memory to be freed automatically. (Note: please do not discuss this hack here, as it comes from a forum we aren’t allowed to talk about or link to.)
•org.nodomain.scrobbled.plist – The Scrobbler daemon. Disable this if you don’t want your music scrobbled anymore.
•com.SPC.SuperCharged.plist – The SuperCharged daemon, which is a virtual memory mod from Cydia. Don’t delete this if you want to keep using SuperCharged.
.
Si todo ha ido bien, al reiniciar tu iPhone deberias notar una considerable mejoria. Moverse entre paginas ya no es una tortura, iBooks es perfectamente usable y las aplicaciones responden como deberian.




eso es todo, yo hice la primer parte, la de borrar las sombras, y la verdad que anda un poco mas fluido el springboard, asi que puedo decir que funciona, la otra parte la verdad aun no lo hice, me da un poco de miedo andar tocando todavia, pero seguro pronto lo hare jejeje, si alguien quiere probar ahi se los dejo.


de mas esta decir que no me hago responsable de ningun daño que le pueda suceder a sus equipos.
