In fact, back in May earlier this year, Rovio was mentioned to be working on an optimized version of Angry Birds for the Nokia Lumia 610, and I guess the fruit of their labor is finally ready to be shown to the world, never mind the fact that it has been a good half year worth of waiting. We do understand that Rovio has successfully optimized all versions of the Angry Birds titles in order for it to play nice with the RAM memory limits of the Lumia 610.
There was no additional information available on just how soon the Angry Birds titles will be available, as the Lumia 610 still gets shown a “unavailable for your device” message, so it might take some more time before the optimized versions show off its feathers in the Store.
