Hello I just found out about the Mewtwo event. Did the event expire yesterday or going on until March 6th, 2012?
Anyways, when I try to recevie the Mystery Gift, I keep getting "There were no gifts to be found..."
I'm also not able to connect to game sync. I'm connecting through WEP and the test connection was fine.
Unfortunately, it would appear that the Mewtwo event actually ended on February 26, rather than March 6, which explains why you were getting the "There were no gifts to be found." message.
There were some miscommunications with the press, as sources such as Pokemon.com said the date was March 6, while others said the date was February 26. But now that the event is no longer going on, it looks like the 26 was the correct date.
There has recently been a flood of people saying that they get the "There were no gifts to be found..." message, despite a working Internet connection. The problem is probably with Nintendo's servers, and I suggest that you call Nintendo at 1800-255-3700 (6am-7pm, Pacific Time, 7 days a week) to alert them of this and have them make Mewtwo available to you.
I am also experiecing the same problem as you. My wifi works fine but i could not get the gift. Anyone knows if the event has ended already? Or isit nintendo's server problem? Thanks. Wish i can get my Mewtwo..
