Just a quick heads up the Nokia “Sleeping Screen” has been updated to version 1.10. This version is has improves compatibility with devices running Nokia Belle on Symbian^3.
This is good news indeed for Symbian users! The sleeping screen is a very useful app and I suggest you download it on your device if you don’t have it on there already.
Just in-case you don’t know what this app does here is the demo from Nokia themselves. (Mind you this is from when it was a Beta app but the basics still apply.)
