###UUID Possible Replacements
- Open UUID
- Is app specific because of keychain limitation
- github source
- Mac Address
- Privacy concerns? (Perhaps just do MD5 hash)
- UIPasteboard
- Bit "hacky" and possibly unreliable
- Should be relatively solid however, still looking.
- iCloud
- iCloud is broken. Plus, the overhead is far too much.
- Solution based on MAC Address
- Seems to work between apps (still looking into it)
- github source
