IPhone 4 sync to more than one computer

I have iPhone 4 that I want to sync iTunes library to more than one computer (1 iMac and 1 PC). PC was previously synced with old device. I want to sync iTunes library currently on iPhone and override data on PC. How do I do this? I do NOT want iTunes library currently on PC and override iPhone.

You do not do this.
Iphone will, and always has, only sync pics and itunes content to ONE computer. IF you sync to another it will erase the current content, then replace with content from the new computer.
This is by design and as intended.
Sorry.

Can my iPhone 4 be synced to more than one computer?

I don't have access to the original computer that my iPhone 4 was synced too. I have a new iPhone 4s due to a contract upgrade, and want to transfer the information from my old phone to my new. However, when my boyfriend has tried to synch it with his computer, by choosing the backing up option in iTunes nothing actually happens. I really don't want to lose the information on my old phone. What can I do please?

The short answer is no. You can't sync to more than one computer at a time.
The longer answer is contained in one of the many many threads about this exact same subject that are already posted in these forums.

Apple won't let me sync with more than one computer

How crazy is it that Apple will not let you sync with more than one computer! I have three computers! One in the kitchen one in my room and one at my parents house. These are all my computers, but if I try to sync my iphone5! with my computer at my parents house itunes says it will erase all my data! I have legally purchased all my music, so I have bought the rights! which means I can have the same songs on mutiply computers.
I've seen posts like this before, so I know Im not the only one who knows that this is unexceptable! Apple knows too! So heres how we gonna do this, **** itunes and **** apple, they can suck it! I'm sick of Apple and how they try to control everything you do, with their limited youtube video capacity because they "dont allow flash".
All Apple care about is taking your money, otherwise they would listen to what their customers are saying. These posts are on an apple site after all.
Thats my opinion, vote this up if you feel the same way.
Thanks

I understand what you mean. If you would have a little more technical background to what is happening when you sync and iOS device, you would understand that the reason for syncing with only one computer is not to control you but is rather to manage the syncing.
For exemple, how would you manage to backup a device on multiple computer while some songs or apps are on your iOS device but not on the computer? Copying them back to the computer would only result in what you don't want, keeping different iTunes library on different computer.
The very best solutions for you is either;
Make one of your iTunes library the master with ALL your media files and use this one for syncing your device. You can easily manage all your music using automated playlist (like one for all the music with an older date you would decide).
Pay for iTunes match and ALL your song (even those you haven't bought from iTunes) to be available in the cloud for you to stream directly to your iPhone. This however have a monthly fee.
I agree that on one thing Apple is controlling; it's by not allowing you to extract songs from an iPod. Giving home sharing now, that would solely restrict you from illegally copying music to others. But again, you must understand that this limitation isn't to be powerfreak, it have been required to secure the music industries and make iTunes Store possible in the first place.
And make shure you active Home Sharing as it will give you full access (stream and copy over wi-fi from any computer and iOS devices) in between your iTunes libraries.

Sync with more than one computer

Is it possible to sync with more than one computer using the same Blackberry Curve 8310? I have a work pc and a laptop and I am using MS Outlook. I've tried syncing to both but the appointments all duplicate themselves. Is there a way to set it up so I can sync to both.

Hello Keithj,
Welcome to the BlackBerry Support Community Forums
You can synchronize with multiple computers but there are a few considerations to take into account when doing so.

Syncing with more than one computer?

Does anyone know if it is possible to sync the iPhone with more than one computer? With the PDA that I used to use I would sync with my secretary's computer also so that we could both update my calendar and conatacts.

You can sync (info - not music/movies) with multiple Macs - not sure about PCs...

Syncing to more than one computer?

Is it possible to sync an iPad to more than one computer? When I first bought it, I couldn't get iTunes to install on my desktop computer, so I used my dad's computer (signed in to my Apple account) to activate my iPad and add about 10 e books I had in PDF form. Now I have iTunes on my laptop (and live in a different house than the original computer) and I want to connect my iPad to it to add some music and photos. Is this okay to do, or will it wipe out everything on my iPad?

I think Apple did think the design through. It was designed to be a single user device linked to one iTunes account and one iTunes library. I know people buy new computers. That's why backing up your iTunes content to an external hard drive or to DVD is a good idea. Then you can transfer your iTunes library to your new computer. Many people just don't think about that.
However, there are ways to get all of your content from the iPad to a new computer. Read this thread that I will reference here below. It has helped a number of users transfer their iPad content to a new iTunes library on a new computer.
https://discussions.apple.com/thread/3305461
Read Demo and King Penguin posts. If you do as instructed, you should be OK.
Remember that you must turn off auto sync in iTunes first, transfer purchases next, then backup the iPad after that. Do not sync before you do those three things.
There are references to third party apps that can help with photos in the thread as well.

Can't seem to sync with more than one computer???

I loaded I-tunes on my laptop and then tried to load on my desktop computer with no luck. Can you only sync through one computer or am I missing something?

If you want to connect and use an iPod on more than one computer you just need to change the update preference in the iPod Summary tab to "Manually manage music and videos". You can't sync from more than one library.

Can the iPhone sync with more than one computer?

Hello, I have a Intel mac book pro and a G4 mac pro. I authorized the iphone on my mac book pro and want to use it with my G4 tower I get a OxE000004 error when I try to sync with itunes to down load my podcasts at work on my G4.

That's interesting. I wonder why it works for me? I was very surprised when it did, I must say. But here's a possiblity: the computer where I sync the videos is my wife's (wanted to get her demo reel and commercials and they weren't on my computer) and she has NO music on her computer. The computer where I sync my music is MY computer, and I DO have videos set to sync to my iPod and a bunch of music, and the computer where I sync my contacts, calendar and email accounts is at work where I don't have any music or videos.
I just sat down at work here and synced my calendar and I still have only 100MB of free space. Last night, I left it plugged into my computer, and I still see the videos that I synced from my wife's computer on it.

HT1535 CAN YOU SYNC TO MORE THAN ONE COMPUTER

I HAVE SET UP MY IPHONE TO SYNC TO MY COMPUTER AT WORK. I NOW WANT TO SYNC MY PHONE TO A LABTOP AT HOME. CAN I USE A DIFFERENT COMPUTER TO SYNC MY PHONE? THEREFORE, IM USING TWO COMPUTERS TO SYNC.

Sync iPod/iPad/iPhone with two computers
Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans with iTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entires and import the local content you have on that box.

Apps syncing with more than one computer

I have read that the apps can be synced with 2 computers. I have 2 homes; each with a desktop computer. If I attempt to sync my Iphone 3GS with the 2nd computer, I get a message that says it will wipe out all the apps on my phone and replace them with the apps in the 2nd computer's library. There are none on the 2nd computer. So, if I sync, all the apps on my phone will be deleted. I do not understand how to sync the apps with 2 computers. They are on different networks (one house in Maryland; another in Florida). Can this be done?

I had a similar problem and the only solution is to keep the iTunes folder on both computers synced - and since your 2 computers are not at the same location - this would mean carrying your iTunes library around on an external hard drive, which I know is not ideal and depending on the size of your library - maybe not possible. In my case, my iTunes library is way too big to keep synced on 2 computers (a MacPro with 8TB of HD space and a Macbook Pro with 250GB of HD dive space).
So the best I can do is transfer whatever iTunes content I want to have on my iphone from my MacPro to my MBP and then if I have to sync my iPhone with my MBP I know that the iTunes content will be the same - even if it is overwritten.
I have mentioned this is these forums before - but it seems strange that Apple can't figure out a way to allow any device to store/play iTunes content that is purchased from the same iTunes store account - be it your phone - laptop or desktop computer. And content that is not from the store - iTunes shouldn't have an issue with.

Can a 3GS sync to more than one computer?

My brother just bought me a 3GS and synced it to his computer to upload all his apps and cool stuff to my phone but I just downloaded ringtones to my personal laptop and plugged in the phone using the usb chord but my Macbook isn't recognizing the device... at all actually.... I am confused. How do I upload these ringtones onto my new phone?

You can only sync with 1 account (Apple ID in iTunes) library. If you sync with a different AppleID, all the apps, music and books in your iPhone will be erased. You have to ask your brother to download the ringtones for you using his computer and Apple ID.

Syncing on more than one computer

Having just got my iPod touch in past few days can I sync cd's on other computers other than my main computer via itunes or will I lose all the information in the library of itunes when I go back to my main computer?

Hello and Welcome to Apple Discussions.
You need to set your iPod to manual to do this.
Select the iPod under Devices on the left hand side. On the Summary tab choose "Manually Manage Music and Videos". From this point you will drag content onto the iPod rather than checking the boxes on the Music and Video tabs in iTunes, but you will be able to do so from multiple PCs.
Merry Christmas

Syncing from more than one computer

Ok, Apple experts, looking for some help. I currently sync my Itouch with my Toshiba laptop, that's where I have all my music,videos etc... I recently bought an Aspire one that I loaded Itunes on, is there anyway to keep all my music on my I touch but sync it with my Aspire one to get new songs and movies added to the I touch while i'm traveling, (basically trying to use the Aspire as my travel notebook, instead of the toshiba)
any help would be greatly appreciated
peace..

Select “Manually manage music and videos” to turn off automatic syncing in the Music and Video settings panes. See “Manually Managing Content” on page 31.
http://manuals.info.apple.com/enUS/iPod_touch_2.2_UserGuide.pdf
Manually Managing Content
The manually managing feature lets you choose just the music, video, and podcasts
you want to have on iPod touch.
Set up iPod touch for manually managing content:
1 Connect iPod touch to your computer.
2 In iTunes, select iPod touch in the sidebar.
3 Click the Summary tab and select “Manually manage music and videos.”
4 Click Apply.
Add items to iPod touch: Drag a song, video, podcast, or playlist in your iTunes library
to iPod touch (in the sidebar). Shift-click or Command-click to select multiple items to
add at the same time.
iTunes syncs the content immediately. If you deselect “Manually manage music and
videos,” the content you added manually is removed from iPod touch the next time
iTunes syncs content.
Remove items from iPod touch: With iPod touch connected to your computer, select
the iPod touch icon in the iTunes sidebar. Click the disclosure triangle to the left of the
icon to show the contents. Select a content area, such as Music or Movies, then select
the items you want to delete and press the Delete key on the keyboard.
Removing an item from iPod touch doesn’t delete it from your iTunes library.
Important: If you delete an item from iTunes, it will also be deleted from iPod touch
the next time you sync.
