just upgraded to ios 8.1.3 but can't get my contacts or calendar to sync with my iPhone 5S

sync using iCloud?

or sync using itunes?

I'm having the same problem. iOS 8.1.3 is not syncing to my computer using iTunes.

Same for me.

Any solutions?

Same for me, now both iPhone & iPad on 8.1.3 and now will not sync with outlook 2010 using iTunes 12.1.0.71 on my PC with usb cable.

All worked fine last week before upgrading devices to 8.1.3.

I found a solution that worked for me:

What I did:

1. Uninstalled iTunes, but didnt need to remove other related software components

2. Downloaded and installed iTunes from here (as you suggested): iTunes 12.1 for Windows (64-bit — for older video cards)

3. I didnt have to reset Sync History or change anything and it works!

Hope it can help you too.

I had the same problem to sync with outlook after upgrading to iOS 8.1.3 too.Mr Malj's solution posted on Feb 17, 2015 1:06 AM works fine for me. Thanks.

I note that several people have had success uninstalling iTunes and reinstalling. Unfortunately, this won't work for me as I'm running OS 10.10.2 on a 27 in. iMac. My iPhone 5S continues not to sync with iTunes. Any ideas?
