When I first bought my phone about a month ago, I synced my Droid with my facebook. I chose the option to sync only facebook friends already in my contacts on my Droid. Then, a couple of weeks ago, before the operating system update, I re-ran the sync and chose to syn ALL friends to all contacts in my facebook. Well this caused duplicate facebook links inside the contacts in my Droid. Duplicate links, multiple links, icons, or whatever terminology you want to call it, or, aka CLUTTER. They all worked and linked correctly but it just looked crummy/sloppy.
So, I called Verizon wireless Droid support. No luck, they did not have a solution, but then came the operating system upgrade for the Droid, from 2.0 to 2.0.1. So, afterwhich, I removed/deleted the facebook sync. Then, I left my phone alone, still running, for a couple hours and performed a battery pull. Then after 5 minutes, I put in my battery, restarted my phone, and re-established the facebook sync. It worked! No more duplicate links or icons inside each contact!
See if this helps. Give feedback. I will follow up with Verizon and have them document what happened to me.
Good luck! Happy Droid’ing!
