My DHD is full of multiple contacts and multiple numbers for single contacts and I'm damned if I'm going through each one bad deleting unnecessary data.

Is there a way to sync my phone contacts to Google, delete them on my computer then force the phone to take the contacts from Google online? Or can this be done using Thunderbird or MS Outlook?

Or an app based solution?

Thanks!

 

They are already linked, but I want to remove multiple numbers under each entry.

For example "Fred" may have 6 numbers under him, each number is identical and the phone says the source of each number is Google

This all seems to have happened after I did a factory reset (as advised by HTC) to fix the weather widget problems since the Christmas update (and it didn't work!)
