I'd like a little more info, too. I have the iPhone feedback page as an icon on my homescreen so I can send off a report everytime Safari crashes. 3 of them today, actually.
when I close out a webapp and there are other webapps open, Safari will show a crash report page, and 9 times our of 10, I'll disregard and go back and reopen Safari. It just seems troublesome to send a report "every time" Safari takes a dump (on my MacBook)! I'm yet to see a crash report on my iPhone.
well, since noone in the poll indicated that they've ever sent one in I guess I don't feel so bad for not knowing what the heck a crash reporter is on the iPhone.
