I can't understand what's happening here..

I have a typical simple contact form... when I test in my mac, on FF or Safari, email gets sent fine..

but on iPhone email does not get sent... I have conventional set up -- submit with submit button, action is JSP that sends email.. (I know this is not most desirable way, but it's worked fine for years, and it's for my personal website, not a lot of traffic, very few "real" emails get sent, no db involved...)

works fine in browsers in computer, but on iPhone email does not get sent... :-(
(I have email code inside a try-block, but no error gets printed....)

would appreciate suggestions..

thank you...
