You might try this Digikey link and look at the various connectors. Might it be a Subminiature, SWD, or SWF type?
I finally got some time to get back to my workshop. After closely examining the back of my phone with a magnifying glass, looking for some other identifying marks, I had an "Ah-Ha" moment. My battery fell out of my phone and revealed three more of the un-identified connectors. I got a closer look at the depth of the connector and with a little help from the link you posted, I think this is the one.
I'm still not 100% on this. I'll need to order corresponding connector to verify it.
Thanks for the help.
