You know the problem -- you want to go back to something you saw in a mobile app, but you either forgot to save your place or couldn't save it at all. What to do? If Microsoft Research has its way, you'll never be left scrambling again. Its uLink experiment creates links to mobile app pages on the fly, helping you find that hotel listing without having to re-do all the steps you took to see it. It's a bit like Google's deep app linking without the need to go online.
