ITunes occasionally reinstalling ALL iPhone apps on sync. Why?

Every few weeks, when I do my daily sync, iTunes will reinstall ALL of my apps onto my phone. I have a lot of apps so this takes a very long time. It doesn't change the data/settings within the apps or the location of the app icons on my iPhone. My iPhone says "Sync in Progress" and iTunes says "Updating Applications on "iPhone"". Thank god this hasn't happened when I was in a hurry. Why is it doing this? Only 4 apps needed updating on this particular occasion.

Well i never. Four more tries, and suddenly - with not changes at either end - it worked.

ITunes 9 removing all my apps at syncing

hello, I got iTunes 9 last night and had no problems at all, I loved it, but when i wanted to sync my ipod touch 2nd gen. 16 gb, even though the app tabs has checked all the apps i want (almost 90 i think), and i got the 3.1 update, iTunes will start removing allll my apps, i have to stop the syncing otherwise i lose them all. When i apply the changes after rearragment sometimes it will show up an alert saying that iTunes will remove 73 apps from my ipod, are you sure to continue?
i haven't seen this problem anywhere, have you? any ideas?

Different iPod but same principle, maybe...
When I first synced after installing iTunes 9, I got the same error message that it would remove my 19 Games (Apps to a Classic)
This was due to a bug in which I had to reauthorize my PC, even thought it was already authorized. After I did this it worked fine.
Now I need to email Apple as I have lost an extra Authorization. Definitely a problem at their end though
Hope this helps

Why is iTunes not showing all iPhone Apps to update?

When checking for updates for my purchased apps in iTunes I sometimes have a few to download - no problem there.
My wife uses the same PC/iTunes but with her own Apple-ID. She can sign in and do the same. Every now and then there are available updates on both Apple-IDs which we can download and sync without any problem. All OK so far.
However, after downloading all available updates for both Apple-IDs and syncing to the iPhone, the App Store on the phone tells me there are more updates. As they are listed on the phone I can check the list against the Apps in iTunes (using get info) and sure enough there are updates available which iTunes does not tell me about. This means I have to update each one on the iPhone to get the updates instead of getting them all automatically using iTunes.
If I browse to an affected App in the iTunes App Store, the button beneath the icon shows as 'UPDATE' even though checking for updates does not identify it.
Using iTunes 10.6.0.40 on Windows Vista with iOS 5.1 on iPhone 4.

I've always assumed those silly strings were recording the results of the gapless playback analysis but whatever they're for it would be better if they were stored in a spare field.
Windows Media Player/Windows Explorer may be less fussy on embedded artwork formats than iTunes or the media file might actually be missing the art but the Windows Explorer cache (Thumbs.db) still shows it. You say removing-reimporting doesn't help but I assume you can still paste new artwork in and have it remembered. If so you might want to use the following tool to at least take some of the effort out of searching out which tracks you need to repair.
*How to find tracks without artwork*
To find all the tracks without artwork so that you can update them you can try http://www.stum.de/itunes-find-tracks-without-artwork/ for Windows or http://dougscripts.com/itunes/scripts/scripts13.php for Macs. Use Google, Amazon, Discogs etc. to locate relevant jpeg images. Ideally these should be square, 320x320 pixels or above and borderless to give the best results in the various menus. If you have artwork for some tracks of an album, but not others, select a track with artwork, right-click (Option-Click for Macs) on the art & click copy, then select all the tracks of the album, use CTRL-I or Command-I to *Get Info* and then paste the image into the artwork box.
I say 320x320 because I believe (from using TouchCopy) that it's the size used in the iPod cache so if you're going to crop or resize you might as well work to that size. Otherwise 200x200 is probably good enough.

Using Itunes, I copied all my apps from my Ipod touch to a new Iphone 4. Problem is all the apps on the Iphone are starting up like a new install. I would think my "password" app and "lose it" app would have the past data transferred to the Iphone.

My iTunes has lost all my apps

Hi,
I recently had my iTunes lost all my apps and podcasts. I don't know what happened, but as far as I know I plugged in my iPhone to sync and charge, and after an hour I came back and iTunes had no apps. Of course syncing my iPhone meant all the apps went from my phone. Any idea what could cause this?
Thanks
Boz

OK, I think I didn't make my original post clear. The files are on the PC, they're in my My Music folder (complete path as you describe).
So yes, I can drag and drop the apps into iTunes, and same with podcasts (although subscriptions are missing). And then do a restore to a backup prior to the mess up. I have done this now, however it means I've lost all app data between the backup and now. Including photos, messages, Apple app data.
Anyway, I've worked around the problem, what I want to know is, how did this happen? Why did iTunes suddenly lose all my apps and podcast subscriptions?
Could it happen again?

All my apps got sync'd to my wifes phone, even the paid ones work

Okay, sorry this is a little long; I have the 3G and my wife has the original, we both use the same computer to sync via itunes using different profiles; never had a problem. I download and installed 3.0.1 to my phone and then connect my wifes phone and do the same with no problems. When I get home from work my wife tells me she can't open any 3rd party apps (they open for a split second and close). So I re-sync her phone and I leave it for a little while, when I get back to the phone, all her apps are gone and all mine are now installed on her phone, paid apps and all. The weird part is, any app that we both had like Splash ID, Facebook, ebay, still had our log-in and other info just like prior to the mix up. The other weird thing is all the apps I paid for are now on her phone and work perfectly and act as though they just got downloaded and being used for the first time, so basically, all her apps got deleted and all mine were installed. My wife has to now reinstall all her apps (which come up as being previously downloaded or paid for). Anybody ever hear of this? Or how to avoid it ever happening again?

Im having a similar problem. Never had a problem until the most recent itunes update, or even the mms update, not sure. But I updated my girlfriends phone for the mms update, and all my apps were synced to her phone. I use the same computer, but we have separate itunes accounts. Tonight, i restored my phone, was having problems, and now i have my apps and all of hers. I did notice that there is a now a home sharing setting, but it is turned off. Any advice would be great. Thanks.

What do you mean " back up my photos or Apps"?
The photo sync is one way - computer to ipad.
You can transfer itunes purchases. Without syncing: File>Transfer Purchases
Copy everything from your backup copy of your old computer to your new one.

Is there any way to get my reminders (from the new iPhone app) to sync with something on my laptop (Mail, iCal, some other desktop app)?

Yes, if you have iCloud set up on your phone and computer, then reminders will be synced through iCal.

ITunes removes new iPhone apps every sync

I occasionally install a few apps directly from the iPhone's app store while I'm out traveling with my iPhone.
When I get back to my Macbook laptop and sync, though, iTunes removes every single app I added.
Fo example, I added AmericanExpress and WalMart on my iPhone last night. When I get back to my laptop and sync this morning, AmericanExpress and WalMart are removed form my iPhone! The apps are in iTunes, and I can re-sync them back to the iPhone, but it's very frustrating to have to take a snapshot of my iPhone every single time before I sync so I can see what apps are removed.
I have SYNC APPS checked and AUTOMATICALLY SYNC NEW APPS in iTunes.
I erased my iPhone and started from scratch (no RESTORE) last week and the same thing still happens.
Is the iTunes app corrupt? Is there a preference I can remove to see if iTunes is the problem?

UPDATE : After trying the user ID login/logout on the iPhone and iTunes, I went to UTILITIES > GENERAL > RESET > RESET ALL SETTINGS on the iPhone.
After the iPhone restarted, I got the animated new iPhone intro and selected "set up as new phone". After pressing NEXT, I was brought back to the iPhone as it was before the RESET. (Nothing was erased, despite the "set up as new iphone" selection.) The wallpapers had changed, and I had to re-sign in to GameCenter and the local WiFi on startup, but all the apps were still there.
I downloaded a free app on the iPhone directly again. (Cut The Rope Holiday GIft). I plugged the iPhone in to the MacBook, went to iTunes, and pressed SYNC.
Cut The Rope Holiday GIft was removed from the iPhone.

How do I reinstall all my apps from the app store to my iPhone?

So I wanted to download a song to my phone so I plugged it into my computer, mind you it's the computer I always use to put music on my iPhone, and I'm using one of my apps while I'm waiting for it to sync. Then the app just crashes or at least I think it crashes. When I go to get back on the main screen ALL my apps have been deleted. And I seriously don't want to download all the apps I had one by one. The only fricking app I had left was tumblr. They're not even saved to my computer anymore. If anyone could help me I would really appreciate it.
Sincerely, ******.

Apps themselves are not part of the backup. Only the app's data is included (presuming the developer followed Apple's guidelines for storing data). You need to resync or re-download the app. Then if you've previously done a restore from the backup, the data should be back as well.
Regards.

Itunes says that my iphone is already synced with with a different library

I have recently reformatted my PC. Stupidly i didnt make a copy of my iphone backup.
now that itunes is now reinstalled onto my pc, when i try to manage my iphone it pops up with a error message saying,
'The iphone is synced with another itunes library. Do you want to erase this iphone and sync with this itunes library?'
the problem is that if i erase the iphone i will lose all my music, contacts, and apps.
is there a way to tell itunes that the old library doesnt exist anymore? and import all the data from my iphone to the pc so a backup can be made?

The iPhone's backup maintained by iTunes does not include any iTunes content and it does not include any photos transferred from your computer to your iPhone.
In regards to iTunes content, an iPhone can be synced or manually managed with an iTunes library on a single computer only, and photos can be transferred from a single computer only. When transferring iTunes content and photos from another computer, all iTunes content and photos transferred from a different computer will be erased from your iPhone first, but your entire iPhone is not erased when doing so.
After reformatting your computer's hard drive, your computer is detected as a new or different computer by your iPhone.
Did you include your iTunes library with your computer's backup along with all other important data before reformatting the hard drive? If not, you should have. The iPhone is not designed or intended to be used as a backup storage device.
iTunes includes an option to transfer iTunes content that was purchased/downloaded from the iTunes store from an iPod or iPhone, but this is for iTunes content that was purchased/downloaded from the iTunes store only.
First you need to re-authorize your computer with your iTunes account with iTunes if you haven't already done so. With your iPhone connected and without syncing, at the iTunes menu bar go to File and select Transfer Purchases From - the name of your iPhone.
Although contacts are included with your iPhone's backup, contacts are designed to be synced with a supported application on your computer. With Windoze, this can be with Outlook 2003 or 2007 along with syncing calendar events, or with Windows Contacts for syncing contacts only - the address book used by Outlook Express or Windows Mail.
If you don't have Outlook 2003 or 2007 available and you don't use Windows Contacts for storing contact info on your computer, before syncing contacts enter one contact in Windows Contacts. Make this contact up if needed, which can be deleted later. This will provide a merge prompt with the first sync for this data, which you want to select. Syncing contact with Windows Contacts is selected under the Info tab for your iPhone sync preferences with iTunes. This way you will have all contact info available on your computer also which should be included with your computer's backup in the event your iPhone is lost or stolen.
