iPhone 4S won't sync new apps purchased on the iPhone, how do I fix this ?

I am having the same issue so +1

I have a similar issue. Bought an iPhone 4S to replace an iTouch. My apps all transfer to the iPhone, but all the associated data does not sync. For example, with one app all the game record data is gone. In another app, all the data I entered is gone. In each case the app works, but all the past data is gone?

What's up with that?

I'm having the same problem with my iPhone 4. Just started having it today. Upgraded to the new OS a few days ago, and this is the first time I've tried to sync since then. Really looking forward to a fix.

I'm having the same issue on iPad2 after IOS 5 upgrade (and iTunes 10.5 (141)). I've been working around this issue by downloading the apps in iTunes first, then dragging them over to the iPad under Devices.

I fixed it. For some reason, iTunes had reverted to my old email address. I switched it to the same one I use on my iPhone, and it synced the new apps. No idea why that happened, however.

Same issue. Nothing to do with dup ID's as I have only had one. Once I sync the apps I've purchased since I've purchased the 4S will not run. I've downloaded them in iTunes, at which point the authorization error stops, but the apps will not run on the phone. I've deleted the app from the phone at which point it will work until I sync again.

Same issue. Opened at ticket for help. There is TS1389 that describes how to fix this, but I tried all the different solutions in that TS and it still doesn't work. I can install apps from ITunes into the 4s, but if I get anything on the 4s it stops transferring apps into ITunes. I checked that my other devices still work. This is only occurring on the 4s.

Anyone else have any solution ideas?

Try this fix. While in iTunes connect your iPhone. Under devices "right click" on your phone.(control-click). choose "transfer purcahses from John Doe's iPhone". After that try to sync again. It worked for me.

I had the same problem, but I figured it out for my situation. I set up my new iPhone with my mobileme ID which is different from my iTunes ID that I make purchases on. When you set up your new iPhone, it automatically signs you into the App Store with whatever ID you set the phone up with...so when I purchased Apps on the phone, they were on a different account than my computer and therefore I recieved the "not authorized" error. I went into settings on my iPhone and changed the App Store account my phone is linked to - problem solved (although I still had to delete and reinstall all the apps).

That was my problem as well. Thanks for figuring it out for me!

That was my problem - though I didn't set up a new phone. My mobile me account is not my store account, so I don't know why my store account was replaced. Maybe something to do with the upgrade when I set up icloud, imessage, etc... Thanks!

I had the same problem as all of you EXCEPT how can you change your Apple ID when it ends in @me.com. The iTunes account on my Dell was set up long ago with an Apple ID ending in @hotmail.com. When I got my iPhone 4S, Sprint set up the phone's Apple ID with @me.com. Thanks to all your posts, I understand that the Apple IDs have to match in order for the apps on the iPhone to transfer to iTunes on my Dell. Unfortunately, Apple doesn't allow you to change your Apple ID if it has @me.com in it. Does anyone have any idea how I can resolve this? Would resetting the phone to original factory settings help or can Sprint change the ID?

You currently have 2 separate accounts - Apple doesn't allow you to alter the IDs or merge them currently. If you share purchased music with your family then multiple accounts may make sense. You can have a separate ID for yourself that is associated with your devices. Then you have the "family account" that you make purchases on. In your specific case the @me.com ID would be your account and the @hotmail.com would be the iTunes "family account". The only thing you need to do is to sign into iTunes on your iphone with the @hotmail.com ID. Future purchases will then be linked to your family account and will be transfered to your Dell when you sync. If you purchased free apps on your iPhone under the other account, I would simply delete them and redownload under the @hotmail.com ID. If you made signifcant purchases under the new account, then you can open iTunes on your Dell, sign in with the @me.com account, and authorize that computer. The new purchases will transfer to the Dell, but it makes your iTunes library a little messier...especially when you start buying new computers.

Option 2 is to restore the iPhone and set it up with the old @hotmail account. This is useful if you do not have a family and don't need the hassle of 2 IDs. I don't know what will happen when you try to set up the phone with a new ID however, since the sim card is already associated with an account. I would visit an Apple store or Verizon to do this so you don't run into any problems activating the phone.

My final caveat is I have not started using iCloud yet so I don't know all the ramifications of having multiple IDs. I'm sure you can search the forums some more to dig up those answers. Good Luck.

Thank you for taking the time to help me with this. I will let you know how it goes this week.

I found out that I had a different iTunes address in my iPhone than I did with my iTunes on my Macbook Pro. I had to authorize both user accounts for my laptop before I could transfer purchases that I had bought with my other email. I don't know why it flip flops between addresses while purchasing apps from my phone, but it does. Hope this helps
