I don't see any ReadItLater related topics on StackApps, our site for applications that interact with Stack Exchange. 

As Ivo mentioned, using favourites is easy. Simply navigate to your profile and hit [**Favourites**][1]. Stack Exchange mobile even supports you favouriting, and will load perfectly. I frequent it using an iPod Touch. You can look over on this page to see [which browsers are officially supported by Stack Exchange][2] - there is no guarantee your mobile browser will function.
