Running iOS 6 and iMessage syncing between iPad and iPhone are sporadic at best. What I send on one doesn't even show up on the other, even after I send a message from the second device. Turned off iMessage and back on again; have all registered phone number and email addresses set. Any ideas how to fix this or is it a bug?

Are the iMessage Apple IDs the same on both devices?

Definitely not a bug. Has worked and been syncing with my phone number absolutely perfect.

It's not perfect, but it works for the most part.

When you go toSettings/Messages/Send & Receive, is the "Start new conversations from" the same on both devices?

Been working like a dream for me.

The start new convos are checked on both for the same account. Some messages are coming across one device while others aren't showing up still.

Try restarting both devices and when they've both connected to the Internet, have a friend send you an iMessage.

I'm on iOS6 on iPhone and 10.8.1 on iMac. Messages were not syncing properly. At least for me, my problem was immediately solved by going to [url]https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/[/url] and adding my iPhone number to my Apple account. Did the same for all the accounts in the family. Now, Messages syncs perfectly, and allows me to keep 'Start new conversations from' on the iPhone as my iPhone number, rather than setting it to match the email address used on my iMac.
