Okay, so I just ran into the first MAJOR bug I've seen on my phone since getting it 6 months ago. I CANNOT add a contact, at all. I go to the people app, choose "Add contact", fill out nothing but the name and phone number, click save at the bottom, and nothing. The contact appears nowhere. It did not get added at all. I can't search for it, it's not in the list. Nothing.

EDIT: I figured it out. It had something to do with how I accidentally had some contacts linked together.
