How to upgrade jailbroken iPhone, and iPod touch

Okay, let say you have Jailbroken your iPhone, ipod touch and get existing jailbreak but you want to upgrade youriPhone from an existing jailbreak, you want to upgrade your iPod touch from an existing jailbreak. Then if you are suffering from difficultly of backing up and restoring some iTunes, so how you can fix these errors?. STop your worrying because this post will guide to help you to do this, as if you already jailbreak your iOS device on older firmware version and want to update it.





Starting Fresh

Please note that whenever you are upgrading to a newer firmware version, always start fresh if you can. You know that most jailbreakers will agree that not restoring from a previously jailbroken backup is the best way to upgrade. The only exception for this rule is if you have to restore (not upgrade).


Before restoring

1. Make sure you have backed up your contacts, calendars, and camera. I use MobileMe so I already know my information will come down. Either store them to your Mac or PC, or use an online syncing service like Google Sync or MobileMe.


2. Check out XBackupTo everytome you save your Cydia packages and settings. There are also other jailbreak utilities that perform similar functions, which one you choose to use, it completely up to you. I’ve had good experience with XBackup.

3. Use an app such as DataDeposit or appbackup to save your in-app game data, you can . Both are free but DataDeposit may be a bit more convenient for some folks as it just saves your data to your DropBox account which is an added bonus.

Restoring

1. Next you’ll want to restore your device via iTunes. (If you are an unlocker, you should probably stray away from this process. You’ll almost always want to use custom firmware bundles to preserve your unlock with a jailbreak utility such as PwnageTool. You’ll want to make sure the firmware version you are upgrading to offers an unlock.)


2. Let your device restore in iTunes and then select “Set up as new device” as opposed to restoring from a backup.


Re-jailbreaking and restoring data

1. Once you have restored your device, you’ll need to re-jailbreak and re-install XBackup and DataDeposit (or whatever two apps you chose to use previously). These should bring down your jailbreak settings and app save data.

2. Now you’ll need to re-sync all of your content via iTunes. Just make sure you selected to set up as a new device.

Re-jailbreaking is definitely not the easiest process in the world but a clean start is always best. I’ve found bad jailbreak bits can come over when restoring from a previously jailbroken device. So doing it right the first time can save you a lot of headaches in the long run. If you’ve done this process or are just trying it for the first time.
