This is one of the most time-consuming ways to speed up and free up space on your iPod/iPhone, but it can be worth it. It involves removing any languages you don't need from the device. I would back up any thing you want to remove (copy to PC before you delete). 1. First, set up SSH. There are plenty of guides on this website. I recommend using a wired connection, like i-FunBox or iPhone browser. 2. Determine which language(s) you want to keep. I'm not sure what all languages are, but I will update this thread when I find out. English would be a folder called en.lproj or English.lproj. 3. Look in the folders below for .lproj folders and remove any unneccesary languages (long method, very tedious but safe, doesn't remove all languages): Code: 1. /Applications: Calculator.app MobileAddressBook.app Cydia.app MobileSMS.app Maps.app MobileCal.app MobileMail.app MobileMusicPlayer.app MobileNotes.app MobilePhone.app MobileSafari.app MobileSlideShow.app AppStore.app MobileStore.app MobileTimer.app Preferences.app Stocks.app VoiceMemos.app Weather.app Web.app WebSheet.app YouTube.app Icy.app DemoApp.app 2. /System/Library/CoreServices/SpringBoard.app 3. /System/Library/PreferenceBundles: AccountSettingsUI.bundle AirPortSettings.bundle BluetoothSettings.bundle ManagedConfigurationUI.bundle MusicSettings.bundle VideoSettings.bundle iPodSettings.bundle CarrierSettings.bundle MobilePhoneSettings.bundle MobileSafariSettings.bundle MobileSlideShowSettings.bundle Wallpaper.bundle MobileStoreSettings.bundle VPNPreferences.bundle NotificationSettings.bundle EDGESettings.bundle ScheduleSettings.bundle WirelessModemSettings.bundle 4. /System/Library/PreferenceBundles/AccountSettings: ContactsSettings.bundle ActiveSyncSettings.bundle CalDAVSettings.bundle LDAPSettings.bundle SubscribedCalendarSettings.bundle MobileCalSettings.bundle MobileMailSettings.bundle MobileWirelessSyncSettings.bundle 5. /System/Library/PrivateFrameworks: AccountSettingsUI.framework AccountSettings.framework AppSupport.framework ChatKit.framework CoreTelephony.framework DataAccess.framework ManagedConfiguration.framework Message.framework CalendarUI.framework DAVKit.framework DataDetectorsUI.framework MobileQuickLook.framework PhotoLibrary.framework iTunesStoreUI.framework MusicLibraryDDB.framework ITSync.framework MusicLibrary.framework OfficeImport.framework Preferences.framework TelephonyUI.framework WebKit.framework WebUI.framework YouTube.framework iTunesStore.framework iWorkImport.framework IAP.framework 6. /System/Library/SystemConfiguration: WiFiManager.bundle PPPController.bundle 7. /System/Library/Frameworks: AddressBookUI.framework AddressBook.framework CFNetwork.framework AudioToolbox.framework CoreLocation.framework Foundation.framework (keep en.lproj) GameKit.framework MapKit.framework MessageUI.framework MediaPlayer.framework Security.framework UIKit.framework SystemConfiguration.framework 8. /System/Library/Carrier Bundles: Fido_ca.bundle Softbank_jp.bundle Rogers_ca.bundle OR in your SSH client, search '.lproj' (without ' '), sort by name, and delete any unneeded languages (short method, risky). While your SSH program is searching, I'd grab something to eat or watch TV for a bit, because depending on the amount of apps and space in your device can change how long it takes for the search to finish. Another way is to run a shell file in Mobile Terminal. This shell file is attached and is made by joeywolfgram. It deletes all languages except English but only in the /Applications folder. Note that this is untested so proceed at your own risk. 1. Set up SSH through this guide. 2. Remove .txt from the end of the file. 3. Copy and paste the shell file into the root of your device. 4. In MobileTerminal or your SSH console, type these commands, line by line: Code: cd / su (type password) rmlan.sh You can save space and speed up your iPod doing this. Other ways to speed up your device are: Use Shortcuts and save battery Limit use of Mobile Substrate applications Remove Launch Daemons Use Virtual Memory (Very Risky) iOS4 Tips: Do not enable iOS4 features on iPt2G and iPhone 3G. Slim down Homescreen wallpapers Install Remove Recents *Credit goes where credit is due. I obtained most of this information from FunkeySpaceMonkey's version of this guide. The 'other ways to speed up your device section' is from various posts from this forum.
