Hi,
with the droplet you can output tiles folder with 3 dimensions set (computer/iphone/ipad),
and checking on screen with iphone simulator software,
it's seems pano looks blurry with iphone 4 (look perfect on monitor screen and with real iphone 3G and ipad, but i don't own a real iphone 4 to check it out) ,
then do we need a additional resolution set only for iphone 4 (don't know if user agent detection script can make difference ? )
or using ipad tiles for iphone 4 ??
