I have an S2 and so far AppGameKit works perfectly on it. It is a very nice phone. Best thing I've bought in quite some time. But you are missing out on the 10 apps a day for $.10 deal.
Things I don't like about the phone:
The back is too slippery (on the black one), but you mostly hold it along the edges anyway. The default launcher could be better (I have ADW installed).
