When I got my new Stratosphere, I imported all my contacts from gmail. For some reason, though, I have a whole boatload of additional contacts that only show up if I want to send a text. These include old mailing groups that I'd set up years ago, etc. How do I get rid of these contacts that only appear when I'm in text mode? My contacts for texting appear to be separate from the phone/email contacts list (they don't show up when I go into the email or phone contacts), and there are literally hundreds that appear when I want to select a contact from text mode. I've tried a long press on each entry to see if I get a delete option (nope), have looked in various settings menus, etc. with no luck. How can I delete these unwanted contacts? I don't want to have to purge all my contacts to get rid of this if I can avoid it. Any ideas???
