Component 1: Something that figures out the user's name and other information.
Can use this technique:
Step 1. Get the name of your iPhone, which is usually something like "John Smith's iPhone"
Step 2. Parse that with a reg ex to match the name
Step 3. (Optional, only if the app wants this, since it involves the contacts data) Scan the user's contacts to see if there's a contact with that name, then get the associated data (phone number, email address, etc)
Component 2: Emoticons
I don't see something for React Native, maybe there is one and I'm missing it. But it'd be cool to be able to do something like < Emoticon type="smiley" />
