I don't have either Samsung i780 or iPhone, but I would expect that iPod
Touch has very similar wlan implementation with iPhone, so I should be
able to test this with that. I'm mostly using AR9280, but I would expect
the issue be more likely in power save mode processing and mac80211.
Anyway, I can also test with AR5416 if no problems show up with the

Quite a few mobile devices have shown odd issues with power save mode in
general, so that would be my first assumption on what could be causing
problems here. Usually this means that using a wireless sniffer to
capture the frames is more or less the first thing to do.. If you can do
that, it could speed up figuring out what is happening. Like I
mentioned, I should able to do this with iPod Touch, but if there is any
different behavior in iPhone or Samsung i780, I don't have an easy way
to reproduce it myself.
