... Yahoo spammers are the reason I won't sync. My addy has been spoofed a couple of times, and since I no longer have any contacts listed, my friends can't be pestered. Some spammers do manage to get contacts in Yahoo.
I also just had a mistaken either Paypal spam or scam in the account I did try G+ with. (Not associated with phone) Not sure if it was mistaken address, or a scam.
Phishbuster say the header was legit. I don't need or want any more. I've banned everything from G+ in Thunderbird with the setup to delete from server when I delete message. I rarely use the web page email, I prefer POP3 or IMAP and a different email app.
So, I sync my PC (I use Outlook for contacts/calendar/email) with my phone directly using MyPhoneExplorer. I sync Outlook's contacts etc with the Google account on the phone BUT have "Google's sync" turned off so that nothing gets out into the "wild".
I use Rocketdialer on the phone set to come up with the 'favourites' screen on first opening. My Favourites screen is, I guess, like a 'quick dial'. Single tap to open favourites then 2nd tap to dial person.
Dunno if that's what you're after? Oh, and I do add piccies but it's not compulsory .....
