Tap and hold is a multi-touch gesture that Apple introduced into Mobile Safari in iPhone OS 2.0. It triggered a popup a menu that allowed users to Save Image to the camera roll.
In iPhone OS 3.0 it’s been given a bit more power. Now, in addition to selecting blocks of text for Copy and Paste, when you tap and hold on a link, you trigger the same type of popup as the Save Image function, but instead you get the URL path for the link and options to Open (in the same page/tab), Open in New Page (tab), or Copy (the URL path).
If the link is also an image, you get all of the above options, with Save Image combined into the mix.
May not seem as sexy as MMS or Stereo Bluetooth but we heart this new functionality. It will make our lives easier, which is what OS updates should do.

We’ve mentioned this in passing before, but the parallels, if any, are worth making more prominent.
Using webOS, which is a localized, almost widget-ized development environment (using HTML, CSS, JavaScript, and enhanced local access), the Palm Pre can run many WebApps at the same time. The way it’s visualized is with the “card” metaphor, where a touch of the Home-like button shrinks the current screen down to a thumbnail that’s kept live and updated in real time. The interface also lets users shuffle the apps like cards in a fanned-out deck. You re-arrange the cards and can even terminate an app by “throwing it away”.
While the iPhone doesn’t keep them live or let you re-arrange them, and has an X to close rather than the throw-away gesture, going as far back as two years ago when Steve Jobs introduced it at Macworld 2007, it let you zoom out of the Mobile Safari web browser with an eerily similar thumbnail representation. (Though there doesn’t seem to be any patent contention over that just yet…)
Actually, given Apple’s recent obsession with Cover Flow in iTunes, OS X 10.5 Leopard’s Finder and now Safari 4 Beta, we’re surprised they didn’t just default to that for Mobile Safari tabs from the get go as well…
