There is a Mew download availible to Heartgold and SoulSilver players that have access to WiFi. This Mew is Lv. 5 and is in a Cherish Ball and is being given away to signify the 10th anniversery of the release of the original Gold and Silver. The event is set to run until Oct 30th.
Also, I know I need to change the Featured Pokemon, but I have been out of town the last week at a conference so I haven't been able to. I will try to get it done either tonight or tomorrow. The Featured Pokemon for October will be Gengar.
