Outdated FAQ?
 

I'm wondering this FAQ: Do you have an iPhone, Android, or BlackBerry app? is still in the FAQ (from 2008)? Isn't this an obsolete answer?

Also this: FAQ: Why do I have to fill the tank all the way up every time I buy fuel? and this: FAQ: Why do I have to fill the tank all the way up every time I buy fuel? , both also from 2008. Seems confusing -- I see the app has a check-off box for "PARTIAL FUEL-UP?" and doesn't that resolve the issues in the question?

I've updated that one.
You linked to the same one twice. I assume you may have meant- FAQ: How do I account for partial fuel-ups? ?
But you're correct, when adding a fuel up we do have a Partil Fill Up checkbox. The FAQ I provided, explains what a Partial is, and the one you linked explains why it's preferred you fill your tank up instead of relying on Partials.
