If its just for looking 'iphone' this might not help. It depends on how your
device sniffer works. If it's just looking for 'mobile' in the string I found


'Mozilla/4.0 (compatible; MSIE 6.0; Windows CE; IEMobile 7.11'

works.

Also check this site out for other short ua strings

Hope this is of some help
