This note describes the operations to a new computer when the iPhone is synced with the old and we hope that future synchronizations are made with the new computer. I remember one
iPhone will sync with one computer. The test was done with two Mac OS X one another, in 10.4 Leopard. However nothing seems to be specific to the Mac world and this should be the same process to two PCs or between a PC and a Mac.
For information, I also a note explaining that it is possible to wait for the synchronization of an iPhone including the transition from a Palm to an iPhone: Prepare for the iPhone and sync with Outlook .
Sync an iPhone
First, a quick reminder about the synchronization process to an iPhone.
syncing the iPhone through iTunes. To date, August 2008, only applications can use Apple iTunes and synchronize. Third-party applications can not use iTunes: Apple offers no API for developers as the FAQ explains the software Evernote.
Accordingly, the synchronization process iTunes is the only one to allow for synchronization with PC:
- the photo: Photo enforcement
- music and video: iPod application
- contacts applications used by phone, call, SMS and email
- calendar: Calendar
- bookmarks from Safari: Safari application
Target applications on the computer are for:
- the photo: Photoshop Album (on PC), iPhoto (on Mac) or record music
- and video: iTunes
- contacts: Outlook (on PC) and Contact (on the Mac)
- calendar: Outlook (on the PC) and iCal (on Mac)
- Web bookmarks: Internet Explorer (on PC) and Safari (on Mac)
For Photos, Music & Video, information on iPhone can not return on the computer. For this information, they must be transferred from one computer to another.
For contacts, calendar and bookmarks, synchronization allows fusion of information between those from the computer from the iPhone. For this information, it is not necessary to transfer information between two computers.
Preparing synchronization of the new computer
The first step is to synchronize iPhone with the old computer: it will have a backup in case of trouble. If you want to retrieve all the appointments calendar, it is desirable in the Info tab to go to the Calendars section , there is a checkbox "Do not synchronize events with more than ...". If the checkbox is checked, the iPhone contains only the last element. If you want to retrieve all the appointments, it will uncheck the box to pass all events on the iPhone.
The second step is to update iTunes on the new computer in order to avoid a compatibility problem due to an outdated version from the version of the old computer. Warning! The update to iTunes on a Mac requires the administrator password on the Mac.
The third step is the transfer of photos from one computer to another: it is copying files. In my case I used a USB key and I did an import images from the USB into the iPhoto application of the new Mac. I created a new iPhoto album to hold all the photos I wanted to have on the iPhone. This mechanism is not very evolved, it was sufficient for me because I was concerned that Photo by thirty.
The fourth step is the transfer of music from one computer to another: it seems that the copy of the directory: HD: Users: UserName : Music: iTunes: iTunes Music suffice. I have not used this method because I wanted to incorporate other music, so I copied my directories as a File -> Add Folder to Library . It is interesting to note that this will select several directories. So, I connected the new computer's iTunes Store (using the old login) and ask for a recovery images of covers: Advanced Menu -> Getting album artwork . This allows for a nice Cover Flow with lots of beautiful pictures.
It may be necessary to repeat a playlist that will be used to limit the iPhone sync to a subset of the library especially if it is very important and beyond the capacity of the iPhone.
Sync with new computer
We connect the iPhone with the new computer. iTunes launches. In my case, I was not in sync automatically. The iPhone appears in iTunes but the list does not fire the Sync not.
It selects the iPhone.
tab Abstract , I checked:
- Only sync songs
- Manually manage music and video
In fact, it is likely that it is not useful to change information. What is important is the Info tab.
tab Info must check:
- Sync contacts from Address Book
- Sync iCal
Those are the cells that trigger synchronization.
In the Advanced category there Replace information on this iPhone , check that are clear:
- Contacts Calendars
Those are the boxes that ensure that the contents of the iPhone will not lost.
Press the Applied .
The following message appears "The iPhone" iPhone UserName "is synced with another iTunes library. Would you erase this iPhone and sync with the other library." Answer Yes.
The following message then appears: "The information on iPhone iPhone UserName "is synchronized with another user account. Would you rather sync this iPhone with the information on this account". Choose the answer Merge .
synchronization starts and a message appears "Syncing with iPhone ... will modify more than 5% of your contacts on this computer.". The message indicates the number of contacts that will be added to the computer. This must match the number of contacts contained in the iPhone.
Press Synchronize contacts .
A new message appears: "Syncing with iPhone ... will result in changes more than 5% of your calendar on this computer. "
Press Synchronize Calendars
Applications iCal and Contacts are updated on the new Mac. The information in the iPhone are stored.
Note that in the Calendars section, there is a checkbox "Do not synchronize events with more ...". If the checkbox was checked, the iPhone contains only the last elements and the application will contain only these events.
Keep passwords
Finally, I give a trick to keep his passwords associated with a Mac. I guess the majority Mac users have never been concerned with the conservation of the Administrator password. Similarly when you create an iTunes account to activate your iPhone, you do not care. This is unfortunately only a few months later, during an update or a change of the computer problem.
What I propose a simple mechanism is relatively safe (ideally biensur never to record their passwords). Security exists only if access to your Mac and your iPhone are protected by passwords.
You can create a contact in the iPhone:
- Name: Account
- Name: Mac
In Item Note you can type the passwords for your Administrator account for the Mac and one for your iTunes Store account.
Take care, all the same password in iTunes Store account that can be used to make purchases on the iTunes Store. In this case, it is better to also protect access to its iPhone by a code. Choose the iPhone Settings application. You have two lines:
keylock. I recommend 1 minute
Lock code that brings a new menu. It allows you to require a 4 digit code (which can be the same as your PIN) to connect to your iPhone. For my part I have chosen Require Passcode after 5 min. This means that if I turn off and I immediately rekindled my iPhone, I do not ask again the password. It asked me if I let it put out more than 5 minutes. This is handy on the subway, where one is forced to turn off his iPhone up and down the train, but where they would also quickly rekindled his iPhone. Conclusion
The transfer mechanism of the synchronization of an iPhone from one computer to another is not very complicated. It requires some time: it is mainly time to copy music between two computers (8 GB to copy what is not instantaneous).
Finally, in a version 2.0 of the iPhone OS, it may be necessary to synchronize the AppStore applications to authorize the new computer (this requires knowing the password to his iTunes account) . To do this, in iTunes select the menu Store -> Authorize Computer ...
I did a post on the feedback portion in 2.0: Experience installing the iPhone 2.0 and 2.0.1 . In the series
