I hijacked someones contacts problem thread in the general droid bionic forum but I'm putting it here for more exposure.
URGENT because I essentially cant access my contacts when I need to...takes minutes
Problem- I had a blackberry in between my D1 and Bionic. All the new contacts I got while on the BB we're obv not backed up to my google account. To resolve Verizon put all my contacts from backup assistant on my bionic. This essentially gave me all my missing contacts....but also created duplicates of everything once my google contacts synced. Contacts introduced from backup assistant WILL NOT back up/sync to my google account for some reason. Thus merge contacts cannot be used on a computer in gmail. Also I now have 1400 contacts or so due to the duplicates...so stock contacts freezes. Also trying to use aftermarket contacts such as GO Contacts to merge doesn't work. It only sometimes populates the contact list, and if i try to use the merge feature its too much for it to handle and I get a FC.
I've gotten suggestions like hard reseting my phone, but I can't do that because I don't want to lose my contacts that were put on it by verizon, and that are not yet syncd to my google acct.
