I finally ran across this free app which works GREAT and solves my dilemma of being able to edit my many phone contacts via interfacing with my PC using wifi. Moto Phone Portal is a dream come true.
Here is a link that tells you all about it, and gives you a download link. I hope it helps many of you here.
Only thing is that it can be a little slow to respond, presumably due to the wifi connection, but at least it works. I went through and associated photos with all my contacts, consolidated multiple phone numbers for a person into one contact listing on the phone, and really streamlined things.
No need to applaud, just throw money.
