If I jailbreak my iPhone 4, is it still Ok to sync it with iTunes (of course, provided I don't click "download and install" when a new version of iOS is available)?

Thanks in advance!

Will the stuff I download via Cydia be backed up same as apps from the app store?

Yes it's ok to use itunes after JB.

No Jail broken app won't backup on Itunes, however some of those app save their data on the user section of the file system which in this case it will be backup by itunes.

And what about if you wish to restore your iPhone? For example, let's say I no longer want to have a jailbroken device? If I restore from a backup created AFTER jailbreaking, will it restore to a jailbroken state or not?

if you restore you loose your JB along with the ability to use cydia and the apps from it. unless you jb again. this is all really basic jb stuff. there are stickies at the top that answer these questions and more.

i think his question is if he restores with a post jailbreak back up, will it mess anything up if he doesnt jailbreak again. being the reason we were supposed to back up before we jailbroke.

if you back up does it replace your prejailbreak back up?

I have this exact question. I am backed up right now and haven't jailbroken my phone yet. After doing the jailbreak, when I sync my phone it will create a new, "post-jailbreak" backup. If I decide to restore to the original settings, will it create a problem using the post-jailbreak backup? If so, how do I keep the pre-jailbreak backup separate so that I can use it if needed?

Thanks for the help.

I was having problems syncing after JBing so wanted to restore to preJB. I had to go back in time machine and restore the back up file. It worked. I cant remember where the file location is at this time. When I do I will post it.

if you want to preserve your non jailbnreak backup in case you ever need to restore to an unmolested backup, rename your phone before you sync it after jailbreak.

What happens when you try to restore using a post-jailbreak backup? Does it not restore completely?

iPhone Backup Location for Mac OS X

in Mac OS X your iPhone files are backed up at the following location:

~/Library/Application Support/MobileSync/Backup/

The (~) symbol signifies your home directory, which is the same place all your other personal documents are stored.

iPhone Backup Location for Windows 7, XP, and Vista

Windows XP stores all of your iPhone backup files in this location:

C:\Documents and Settings\user\Application Data\Apple Computer\MobileSync\Backup

Windows Vista and Windows 7 backs up the iPhone files to here:

C:\Users\user\AppData\Roaming\Apple Computer\MobileSync\Backup

Obviously if your main drive is not C: then you’ll have to change that, same goes for ‘user’

Note to Windows users: the Application Data and AppData directories and their contents (iPhone backups included) are considered ‘hidden’ so you will need to enable ‘Show hidden files’ within Windows Explorer before you will be able to see the files.

Sorry to keep asking, but I haven't seen an answer yet. Is it generally advised to restore with a pre-jailbreak backup, or can you just restore with a backup that was created after jailbreaking?

Thanks in advance.

I have been searching this, too, with no definitive answer yet. From what I have read, restoring a backup made after JBing can leave 'remnants' of the jb that may or may not cause issues. Can Apple see these leftovers if I have to bring the phone in? What are the issues it can create? How do you safely backup only the official apple stuff after jailbreaking so you can go back to a fully UN-jailbroken phone if you want?

Yes some things CAN remain behind. If you make changes to carrier logo, some signal bars mods. Anything left behind is just mostly cosmetic stuff. Apple isn't going to dig into the file system to find little bits and pieces of a leftover JB but they will notice anything in the UI that sticks out as being JBn'.

The way to avoid this is after you restore to a official firmware (when/if you no longer want a JB phone) is to set the phone up 'As New' instead of restoring from a back-up.

OK thanks for the thoughtful reply, instead of the typical "use the search" I was afraid of, especially since I did search!

So if I JB and only use apps that don't actually change anything on the phone, I can safely backup and use that backup, even after going back to an unJB state?

Are there many reports of backups made while jailbroken causing trouble? I have only read people stating that it could cause issues, but no actual reports of problems.

Thanks!

Yeah it could cause problems but your right I can't think of any right off the top of my head besides the UI changes that stick. Not wearing your seatbelt could get you killed too, one of those kind of things. Not sure what your worried about though. If you're worried about going from JB to a non-JB phone and having problems with backup's it's not really likely to cause a problem plus you don't have to restore from a backup so it's moot. Yeah you'll lose your saved SMS's and phone call lis if you set it up as new but everything else can be put back on the phone easily.

If you worried about having to take it into the Apple store again it's easy enough to restore to a blank brand new phone state with no detectable Jb traces. You'll want to do that anyhow if you ever have to take the phone into the store for exchange so your information isn't on the phone.

So the question I have is. If I was to restore from a blackup in itunes with my jailbroken Iphone 4, I can safely do this, and it won't effect the jailbreak, etc? I accidentally deleted an app that's no longer avail from apple, so I want to restore from backup to get it back.

Ok...so to answer your question ....yes..you can safety restore the backup and it will not affect your Jailbreak... HOWEVER>>>

The App themselves don't get backup, iTunes backup your user data, settings, message etc, if the app is not longer available on iTunes and you deleted it, the app is gone.

Thanks, the app still shows within the itunes library, but is unchecked. WHen I deleted it, I deleted it from my "phone". So, I think all I need to do is just put a "check mark" on the app, and it will put it back, and from what you said, I won't lose the jailbreak.

Oh yeah if the app is still there, it should sync it back up, no need to restore from backup, and had nothing to do with jailbreaking.
