After upgrade to iphone OS 4.0 (and then 4.1) correct sync stop working

Question

After upgrade to iphone OS 4.0 (and then 4.1) synchronization of calendar, contacts, bookmarks of safari STOP working. For example I check checkbox "synchronize calendar" and press "apply". Then iTunes DELETE check in the checkbox ("synchronize calendar") and start synchronization of all other info but not calendar. The same situation with contacts, bookmarks, Mail.
How is this problem resolved? Thanks in advance.

Answer 1

It's OK--no worries! Mail accounts sync differently (I'm a MobileMe user) so knowing the mail account type is important.
First, repair your permissions. You can do this by opening the Disk Utility (Applications to Utilities to Disk Utility), selecting your hard drive and then clicking "Repair Permissions."
Than, rest the iPhone by holding down the "Home" and "Power" buttons through the home screen until the apple appears. Then let it come back to your home screen.
OK, second, I looked up the iOS 4 Manual. Double check your phone settings. Under the "Setting" button, select "Mail, Contacts and Calendars." Select the accounts on your phone and make sure the syncing for the items you want to sync is turned on.
I know you've done this, but try it step by step in case something was left out:
From the manual . . .
Set up iTunes syncing:
1 Connect iPhone to your computer, and open iTunes.
2 In iTunes, select iPhone in the sidebar.
3 Configure the sync settings in each of the settings panes.
See the following section for descriptions of the panes.
4 Click Apply in the lower-right corner of the screen.
By default, “Open iTunes when this iPhone is connected” is selected.
iPhone Settings Panes in iTunes
The following sections provide an overview of each of the iPhone settings panes.
For more information, open iTunes and choose Help > iTunes Help.
Summary Pane
Select “Open iTunes when this iPhone is connected” to have iTunes open and sync iPhone automatically whenever you connect it to your computer. Deselect this option if you want to sync only by clicking the Sync button in iTunes. For more information, see “Automatic iTunes Syncing” on page 58.
Select “Sync only checked songs and videos” if you want iTunes to skip unchecked items in your iTunes library when syncing.
Select “Prefer standard definition videos” if you want iTunes to sync standard definition instead of high definition videos (iPhone 4 only).
Info Pane
The Info pane lets you configure the sync settings for your contacts, calendars, email accounts, and web browser.
Contacts
Sync contacts with applications such as Mac OS X Address Book, Yahoo! Address Book, and Google Contacts on a Mac, or with Yahoo! Address Book, Google Contacts, Windows Address Book (Outlook Express), Windows Contacts (Vista and Windows 7), or Microsoft Outlook 2003, 2007, or 2010 on a PC. (On a Mac, you can sync contacts with multiple applications. On a PC, you can sync contacts with one application at a time.)
If you sync with Yahoo! Address Book, you only need to click Configure to enter your new login information when you change your Yahoo! ID or password after you’ve set up syncing.
Calendars
Sync calendars from applications such as iCal on a Mac, or from Microsoft Outlook 2003, 2007, or 2010 on a PC. (On a Mac, you can sync calendars with multiple applications. On a PC, you can sync calendars with only one application at a time.)
Mail Accounts
Sync email account settings from Mail on a Mac, and from Microsoft Outlook 2003, 2007, or 2010 or Outlook Express on a PC. Account settings are transferred only from your computer to iPhone. Changes you make to an email account on iPhone don’t affect the account on your computer.
Note: The password for your Yahoo! email account isn’t saved on your computer, so it can’t be synced and must be entered on iPhone. In Settings, choose “Mail, Contacts, Calendars,” tap your Yahoo! account, and enter the password.
Web Browser
You can sync bookmarks on iPhone with Safari on a Mac, or with Safari or Microsoft Internet Explorer on a PC.
Notes
Sync notes in the Notes application on iPhone with notes in Mail on a Mac or with Microsoft Outlook 2003, 2007, or 2010 on a PC.
Advanced
These options let you replace the information on iPhone with the information on your computer during the next sync.
When you plugged the iPhone into the new macbook (figuring you had the iPhone first and then got the macbook), you should have received a message saying that your iPhone was currently syncing to another itunes library and do you want to sync it to this one. Did you get that message and did you click "yes?"
Hang in there, you'll get it. My two gmail accounts are syncing OK. I don't use google calendar or sync contacts to those accounts.
