What folders and files gets backed up through iTunes?

Everytime I get a call my old wallpaper shows even though I have a new one. I'm trying to find it on my开发者_C百科 iOS but I cannot seem to figure out where. So I'm trying to track down what folders gets backed up when i backup my iPhone since I have restored it and it's still there. (I'm using a jailbroken device)

I know this isn't the actual folder names and etc but it will give you an idea what it's backing up though. Good Luck.

With iOS 1.1 and later

• Safari bookmarks, cookies, history, and currently open pages
• Map bookmarks, recent searches, and the current location displayed in Maps
• Application settings, preferences, and data
• Address Book and Address Book favorites
• Calendar accounts
• Wallpapers
• Notes
• Call history
• Mail accounts
• YouTube bookmarks
• SMS messages
• Saved suggestion corrections (these are saved automatically as you reject suggested corrections)
• Camera Roll (photos and screenshots taken by the iPhone)
• Voicemail token (This is not the Voicemail password, but is used for validation when connecting. This is only restored to a phone with the same phone number on the SIM card.)
• Web clips
• Network settings (saved Wi-Fi hotspots, VPN settings, network preferences)
• Paired Bluetooth devices (which can only be used if restored to the same phone that created the backup)
• Keychain (this includes email account passwords, Wi-Fi passwords, and passwords you enter into websites and some other applications. The keychain can only be restored from backup to the same iPhone or iPod touch. If you are restoring to a new device, you will need to fill in these passwords again.)

With iOS 2.0 and later (in addition to the above)

• Managed Configurations/Profiles
• List of External Sync Sources (Mobile Me, Exchange ActiveSync)
• Microsoft Exchange account configurations
• Nike + iPod saved workouts and settings
• App Store application data (except the application itself, its tmp and caches folder).

With iOS 3.0 and later (in addition to the above)

• Videos in Camera Roll
• Per app preferences allowing use of location services
• Offline web application cache/database
• Voice Memos
• Autofill for webpages
• Trusted hosts having certificates that cannot be verified
• Websites approved to get the location of the device
• In-app purchases

New with iOS 3.1: Videos in the Camera Roll that are 2 GB or larger are not backed up (iOS 4 and later will back up videos 2 GB and larger)

All user documents and settings get backed up, Application settings as well as system settings.

Applications each have a Documents folder that user data can be saved to, so thats pretty much what gets backed up for applications, including app preferences.

These are the Wallpaper locations:

/private/var/mobile/Library/SpringBoard/HomeBackground.jpg
/private/var/mobile/Library/SpringBoard/HomeBackgroundPortrait.jpg
/private/var/mobile/Library/SpringBoard/LockBackground.jpg
/private/var/mobile/Library/SpringBoard/LockBackgroundPortrait.jpg

I have manually managed to find out what gets backed up and managed to solve the problem :) I downloaded the trial of iphone packup extractor http://www.iphonebackupextractor.com/ and found what I was looking for.

Also it seems like I just had to change the lockscreen in the iPhone since the file called LockScreen.jpg was the picture I was looking for but since I had another lockscreen using winterboard I didnt think of this.

Good luck to anyone else who has problems similar to this.
