Two iPhone sharing apps stopped working

What do you mean by "just doesn't work"? What happens in vagueness, stays in vagueness!

I have a similar problem. My old iphone 1 was stolen; I'd like to put the apps from that onto a new iphone 4. I'm managing this new phone with another computer, and have a new appleid. But, I'd hoped I could install the old apps on the old computer onto it. However it does not seem to work. I had trouble changing account on the iphones (to the old appleid and back again to the new one) before and I'd like to avoid it if there is another way to do this.
I read that you can only manage the iphone from one computer. Might this be the problem? (But if your computer dies or is replaced, there must be a way to change computers.) I thought you could install the purchased material onto 5 devices, so I did not think this is the issue.
But since you are having a similar issue with intalling the apps onto 2 devices, maybe that is no longer allowed?

If you're using a different Apple ID than unfortunately there's no way of keeping your previous apps...

Still unclear if you and your wife have different iTunes accounts. You can't have apps/media purchased from more than one account on the same phone.

You can have the same account on 5 different computers, but can sync an iPhone with only one at a time. Unless all computers have identical apps/media itunes libraries, what's on your phone gets replaced with what's in the computer's library you're syncing with.

I have the same problem.

My new iPhone4 was delivered yesterday, I noticed after syncing for the first time that none of my previous Apps had copied over to the iPhone4.

Again previously my partner and I had had no issues 'sharing' Apps between our iPhones. We both use the same iTunes id and it was the same one I used to activate my new phone. I just can't pick up my Apps on the new phone.

Any ideas??

Yes we have different iTunes accounts. Again to be completely clear, music that is bought on my iTunes account can be played on her computer as well as synced to her iPhone 4 because her computer is authorized. Therefore it is false to claim that each phone is limited to media from a single iTunes account. It is only apps that will not sync.

What i actually said is that you can't have iTunes media from 2 different accounts on a single phone *_at the same time_*. You can sync any phone to any iTunes account and the music and apps purchased in that account will replace whatever is on the phone.

Furthermore my apps are also synced to my brothers iPhone 3GS so I know this has been possible with the iPhone 2G, iPhone 3G and iPhone 3GS.

Yes, but they replace his apps from his account. Again it is not possible, without hacking/jailbreaking the phone, to sync apps purchased from different iTunes accounts on the same phone at the same time.

I will do additional research to see if this behavior is iPhone 4 specific or related to newer iTunes versions.

This behavior is as designed by Apple, and is the same for all iPhone models, iOS and iTunes versions. Any i Phones that can have apps and media from more than one iTunes account at the same time had to have "unauthorized modifications" and can't be discussed in this forum.

Well, that statement is absolutely not true. Fact is you can share iTunes content from different accounts on different devices. I do this all the time with my wife. Perfectly legal & permitted under the EUSLA.

So, you're saying that when you sync your iPhone to your wife's computer or iTunes account, her apps/media are added to your phone and don't replace what's already in it? If so, how do you accomplish this without having already added your media into her iTunes library?

Here's what you have to do to share content(only permitted by the EUSLA among family members, in the same household, up to 5). iTunes has home sharing built in, you can do it that way, or:

Let's say I want to share apps with my wife, she has her own computer & iTunes account:

1. Disable auto sync when an ipod/iphone is connected in her iTunes on her computer.
2. Sign her out of her account, sign in using my account details.
3. Connect MY phone...you do not want to sync, obviously.
4. Store>Authorize this Computer(you only have to do this once).
5. File>Transfer Purchases(all purchased content on my phone will be transferred to her library).
6. Eject my phone.
7. Sign out of iTunes & sign her back in.
8. Connect her phone & select what content you want to sync to her phone.

All app updates have to be done using my account, sign her out, I sign in, update the apps in question, sign out, sign her back in.

Been doing this for years this way, although home sharing makes it easier.

Yes, this works - that's what I meant by adding your content to her library.

However, that's not what the OP is talking about. He claims (or seems to be) that he used to be able to simply sync apps and media from his wife's account, adding to his account's media/apps already on the phone but can no longer do so. He wasn't referring to the transferring of purchases from the phone to his relative's iTunes accounts, and then syncing the combined libraries (yes, a lot easier with home sharing).

I upgraded my wife from a 3G to a 4 on release day.
I have a 3GS.

We shared dozens of apps between the 3G and 3GS using independant accounts. They were shared using the oldschool copy method and the new, easier shared library method.

After upgrading her to the 4 everything still continues to work just like it did before. i.e. requiring the credentials of both accounts in order to update apps.

I'm not 100% certain, but I don't think I've yet shared over a new app in the purely 3GS to 4 scenario. Maybe that's a clue...
