Why can't I flag a question or answer when I'm on my iPhone?

Because the iPhone app was originally only meant as complimentary to the real thing. Obviously, the space constraints forces the developers to leave out some stuff.
Though I suppose with the extreme popularity of the iPhone app it probably receives more love. Or should I say lurve? :)

Lurve!!! I lurve it! Good answer though. I wish I’d had a flag button on my iPhone this morning…

wow, wow, wow…... What about good question? I’m hurt.

My apologies!!! I did give you a Good Question point though!

Thank you hairypalm for asking such a tremendously awesome question!!!

Fluther get revenue from ad impressions. There are no ads on the iPhone version, therefore no revenue, therefore not all of the features are present.

Just a guess.

LOL I was kidding, but thank you! Not enough people use the great question button. Should that button be bigger?

That button should also be present at the bottom of the page so you can see it after you’ve answered a question ;-)
