Since "upgrading" to iOS 4, MobileMe Calendar Syncing has stopped working. This is the worst upgrade. Slow iPhone, spotty usability, and now MobileMe syncing isn't working.

Anyone else having the same problem? Any fixes. I've tried the usual. Push: On, MobileMe Sync: On, etc....

MBP, Mac OS X (10.6.4)

    I'm having the same issue! Tried a bunch of things, but the only thing that works is removing and then re-syncing mobileme calendars (hardly practical)...

    I have had major problems with syncing with MobileMe since ios4 update. I picked up a brand new replacement 3G iphone, updated iTunes software and then updated ios4 - issues started immediately. I have spent nearly three hours getting online MobileMe support but have got nowhere. Changes to iMac have not been updated to MobileMe e.g. calendars and contacts. I have tried everything and the online help has suddenly ceased when they could not resolve it.

    Also - phone is now very sluggish and calendars have long annoying delay - goes blank and then reloads over several seconds. A number of other problems but too many to list. What a headache!!!

    Like you, I ran into MobileMe synchronisation problems after I upgraded my iPhone’s software to iOS 4. I have an iMac running under Mac OS X version 10.6.4 and a 3G iPhone. I was able to solve the problem with the following “brute-force” (but very simple) sequence, which I also used after prior iPhone software updates and it has always worked for me. Note that it involves the removal of all contacts and calendars from the iPhone so if you are worried that you may not succeed in copying the data back, you may want to look for another solution.

    (1) Make sure that MobileMe is synchronized with iCal and Address Book:

    Open MobileMe Sync Preferences
    Click on the “Sync Now” button

    (2) Back-up the data in the iCal and Address Book applications (just in case):

    File / Export / iCal Archive
    File / Export / Address Book Archive

    (3) To avoid erasing the data on the computer if something goes wrong:

    Open MobileMe Sync Preferences
    Select the “Sync” tab
    Un-check “Synchronize with MobileMe”

    (4) On the iPhone:

    Settings / Mail, Contacts, Calendars
    In the “Accounts” section, select the MobileMe account
    Turn “Contacts” off
    Select “Delete from My iPhone”
    Turn “Calendars” off
    Select “Delete from My iPhone”

    (5) Check that all contacts and calendars have been deleted from the iPhone, then do:

    Settings / Mail, Contacts, Calendars
    In the “Accounts” section, select the MobileMe account
    Turn “Contacts” on
    Turn “Calendars” on

    (6) Wait (it may take a while) until all contacts and calendars have been updated on the iPhone, then do:

    Open MobileMe Sync Preferences
    Select the “Sync” tab
    Check “Synchronize with MobileMe”

    After having done all this, changes made to contacts or calendars on the iMac or iPhone were properly synchronized with MobileMe. You may have tried something similar without success, but if you have not, hopefully the above will work for you too.
