It's probably worth using the deprecated/retired comment format from other IDs,
as in line 142-148.

[justincohen, 2014/02/14 23:20:51]

Done.

Do you prefer _UNUSED, or the _MIN/_MAX format the suggest IDs use?

[justincohen, 2014/02/14 23:20:51]

I went with MIN/MAX.  I wasn't sure what to name it, tho, does
IOS_PHONE_NEW_NTP_2014_Q1_ID_MIN and IOS_PHONE_NEW_NTP_2014_Q1_ID2_MIN make
sense?

It seems a little odd.
