<< Awesome! Using a screen capture utility to talk about those built into the OS. >> Heh-heh ... very funny! But true ... the one thing we can not do with the built-in screen capture capabilities is a quick and painless way to do annotations into the capture. The one I prefer for this purpose is Skitch (available via Evernote.com and the Mac App store)... the newer version 2.x is OK, but the older version (before Evernote put their hands on it) was easier and had some additional features, now gone.
<< do you know how to edit the Favorites list?>> On the iPhone, go to the Phone app. You'll see a row of icons at the bottom, the left-most is the Favorites. Tap that and you can add from your Contacts by tapping the + button at the top-right. Use the Edit button to sort the entries and to delete entries.
There's this big trend now-a-days for so-called bloggers and "journalists" to tell us how to work our tech. Sorry, but I don't need the lecture. I use common sense, and that includes ignoring incoming calls. If the person I am talking to takes a call or texts, I just leave.
