My iPad and iPhone are not syncing my notes, contacts and calendars

Have you turned on iCloud and set it to sync these databases? Go to Settings>iCloud. Do this on all devices.

Wait, you have an iPhone 3G? You need iOS 5 for iCloud and a 3G can't upgrade to iOS 5.

i have done this before. It seems since my last update they are not syncing. I have a iPad 4&iphone 5 S. Appreciate any suggestions u have

Hello

Notes, Contacts and Calendar event can come from other sources too.

> Email accounts Like Gmail, Outlook ....

> Social Media, like FaceBook Twitter ...

> Apps you might be using.

Are each of your devices signed in with each account, that could be used to sync them?

Best of Luck
