I have a Samsung Galaxy S2 (running Gingerbread 2.3.3) and enabled syncing of contacts for Facebook, Twitter, LinkedIn and Google. I've been finding it really annoying that when I go to write a message I start typing in a name and I get a bunch of e-mail addresses from Facebook, etc - people who are not in my main contact book and that I do not want to contact from 'Messaging' on my phone.
I have tried setting the option where only contacts with phone numbers are displayed but I think this only applies to the 'Contacts' application and not messaging. Any ideas?
