Hi Steve,

I did some research on this. It is a known issue that Safari on iOS does not currently have a way to visually display the title attribute. I can't reveal anything about plans for future releases at this time.

It should be noted that VoiceOver on both Mac OS X and on iOS will read out the title when activated. So although title is not currently a great choice if you wish to support touch UI on iOS, we do make its contents available to VoiceOver users.

In addition, Safari on desktop with VoiceOver enabled will visually display everything that's read, and allow anything on screen to be focused using the "VoiceOver curser"; this includes even elements that are not ordinarily focusable. So by enabling VoiceOver and muting it, it is also possible for users who have difficulties using a pointing device to see the contents of title text. VoiceOver on iOS does not include the visual display, so it does not provide this same feature.

Hope this helps,
Maciej
