How to Sync Your Google Calendar and Your iPhone Using OS4

Please Share...Twitter0Facebook0Google+0LinkedIn0Pinterest0tumblrStumbleUpon0Reddit0Email

When Apple first released OS 2.0 and 3.0 for the iPhone, people were able to sync their devices with the Google servers, easily allowing them to access and edit their contacts and calendars. However, when they updated to 3.1, Apple broke the sync, leaving thousands in the dark. After finding workarounds, people were again able to sync their systems, and the world was a better place.

However, after releasing 4.0 on June 21st, Apple, yet again, broke this new workaround, leaving people without the possibility of syncing their iPhone, iPod Touch, and/or iPad to their Google Calendars. After losing all of my calendar information (which has really hurt my productivity), I started to mess around with various settings, finally finding one that, once again, lets me sync my GCalendar with my iPhone. As a nice person, I figured that I should help you out, as I am sure that this is a common problem.

To resync your iPhone, iPod Touch, or iPad, simply do the following:

  • On your device, go Settings
  • Navigate to Mail, Contact, Calendars – Add Account – Other – Add CalDAV Account
  • Once in the CalDAV settings, enter the information from the following picture (your username ad passwords should be the ones that you use to access your Google account):

  • Tap Next
  • Navigate to your device's Calendar
  • Click Calendar at the top left of the screen
  • Unselect all but the one under the 'www.google.com' header – if you do not do this, you will be able to see events from your GCalender, but not be able to add any.
  • If you have multiple calendars on other accounts, simply add them the same way. If you have muliple calendars on one account, go here and select the ones you want on your iPhone. Then, when entering an event, you can pick the calendar it goes on at the bottom of the event editing screen.

At this point, your system should be set up. I would recommend checking with some test events, but everything should connect (it might take a few minutes to transfer from one device to the Google server, and vice-versa). If you add, alter, or delete any event on either your device or your Google Calendar, it should update quickly on the other. Even if you are in airplane mode, when you reconnect, all changed events will show up.

This workaround worked very well for me, and I hope that it works well for you too. If it doesn't, let me know in the comments, and I will try to find out why. Other than that, see you all next time Apple updates their software.

    After wasting 4 hours trying to see why my set up does not sync, yours is the only updated ( shame on google docs HELP ) which explains that the sync does not work due to the OS update… It works for me finally! Thank you so much!!

    When I have put all the details in as per your picture my phone trys to verify calDAV but comes back sayimg unable to verify account.

  • michelle Griffith

    I forgot to add that then I save it anyway and go back into it but it has no password in the screan so I put in my gmail password and it comes back saying password incorrect. It is the correct password though. I had the same problem when I tried to add another email account when I first got my phone and had to use my gmail account instead

    Much easier way!!! AND YOU CAN ADD EVENTS TO ALL YOUR DIFFERENT GOOGLE CALENDARS!!!

    1) On iPhone: Settings -> Mail, contacts -> add account-> microsoft exchange:
    2) Email = full google email address; domain = leave blank; user = full google email; pass = google pass; description = whatever you want your google account to show up as on your phone (IE “google” or “Primary”)
    3) Once it verifies, there will be a “server” section; put in m.google.com
    4) Once it verifies again, you have to option to sync mail, calendar, contacts. I suggest you dont do contacts, but if you want to, BACK UP CONTACTS FIRST, you can mess with this option later.

    Once all that is done, in safari in your iphone, open m.google.com/sync
    check the calenders to sync and click save.

    Thats it! Open your calendar on your iphone and all your google calendars should be there AND you should be able to choose which calender to add events too!!! It took me a long time to figure this out, but I LOVE that it works now!!! Finally!!

    Thanks a lot.
    It worked perfectly on my iphone4.
    For soem people: username should include “@gmail.com”

  • ODU

    This was so helpful. Thank you. I’ve been trying everything to make all of my various google calendars show up and couldn’t get anything to work!

  • SSS

    So by syncing the google calendar and iphone calendar together, it is my understanding that I am not able to use my iphone to input information into the calendar anymore? This makes it rather useless!

  • jakbkk

    this works great!!!! i setup a 1-way sync of Google Calendar with my Outlook Calendar so now i don’t need a stupid iTunes sync to get my Outlook Calendar on my iPhone!!!!

    THANKS THANKS THANKS

  • apple

    Thank you! After going into an apple store and no one being able to assist, I am relieved to find this. I followed the steps and found that I had to select both the @gmail account and the http://www.google.com account in order for it to sync. But, it works now!

  • Steve

    Thanks bud.

  • Evelina

    nice article. You know, I’m using ,,Plan”. It Sync my todos on th go to Cloud :)

  • A.J

    It worked! Thank you. I just changed over to the iPhone from Blackberry, things are different. One thing I’m not pleased about is setting up a group to send a mass text. Apparently, iPhone doesn’t allow for this. Do you have a work around for that. A million thanks!

  • Chris

    Many thanks for this. It worked. I wasted a few days on this problem. You provided the solution. I am most grateful.

  • John Goodman

    Thanks very much for this – it worked perfectly. But have you ever worked out how to sync the tasks function in Google Calendar so that also appears in the iphone calendar?

  • Peter Titchener

  • nora

    thank you so much! life saver!!! :)

  • Steve

    Thanks a million! All other attempts to fix this failed- I think in an attempt to make me only use iCloud- but I need access on google as well. Thanks for this clear article.

  • Marque

    You are awesome! Thank you!

  • mkk

    Thank you! That had been bothering me for a long time.

  • Sheryl

    I followed the directions but when I typed in the information in the CardDAV, it said that the account could not be verified. What do I do now?

  • apple/google shouldn’t be so difficult

    Thank you; it worked!

  • damia129

    Thanks, this was a lifesaver!

  • Michael

    Even easier yet :

    That’s it!

  • Rovin

    THANK YOU THANK YOU THANK YOU!!!!

  • Micki

    I’ve been trying for WEEKS to get iPhone and Google calendars to sync both ways with no success. Couldn’t get Google calendar to pick up events on iPhone. Finally, something that worked! Thanks SO much!

  • Jennie
