Just when you thought it was all over by completing the festive variant, Rovio go and release an update to Angry Birds for Symbian^3 handset owners. With two new level packs (Danger Above and Big Set Up), Golden Egg support and some tweaks to the UI, the fowl flyers are set to keep you frustrated into 2011.

Users will need to hit the "check for updates" button on the main screen of Angry Birds and download the new installation file. Then they'll have to exit Angry Birds, launch the File Manager, click on the downloaded file,  and confirm the install. After all that, v1.4 (2) will be waiting for you!

Simple. Probably.

Here’s the thing though, this shouldn’t be news. Developers should be able to have a simple (and standard) alert mechanism for new versions of their application via the Ovi Store. While we’re told it is in the roadmap, it’s going to be left to the users checking for updates (either online or through an in-app system) for quite a while.

Anyway, that’s an issue to discuss for another time. Right now I’m off to check out the new levels and Golden Eggs on offer…
