Q: After 9.2 upgrade, iPhone 4s does not sync my contacts

Hey there PKS1,

I see that you are having some issues with Contact syncing through iTunes on your Windows computer. Here is an article for you that will help you address this issue with some troubleshooting steps:

Calendar, Contacts and Reminders

If you need help with your Calendar, Contacts and Reminders with iCloud for Windows, try these steps. 

When you open iCloud Reminders on your Windows PC, they're labeled Tasks and appear within the Tasks section.

Turn iCloud Calendar, Contacts and Reminders off and back on

1. Close Outlook.
2. Open iCloud for Windows.
3. Deselect the Mail, Contacts, Calendars & Tasks checkbox and click Apply.
4. Wait a few seconds. Select Mail, Contacts, Calendars & Tasks, and click Apply.
5. Open Outlook.

Make sure that iCloud isn’t your default account in Data Files

When iCloud is set as your default account in Data Files, your data won't sync between your devices. 

Outlook 2010 and later:

1. Select File > Info > Account Settings > Data Files. 
2. If iCloud is listed as the default account in the Comments column, select a different account.
3. Click Set as Default.
