Don't forget that Feb-May is the maximum time from a new iPhone release. This quarter saw an actual release so I wouldn't be surprised to see them snatch back the 1%. More importantly you can't extrapolate from just the one quarters figures :) Android sales could trail off or people could end up sending them back in high numbers after a few months etc.
Also, Android is offered on a wider array of phones; so it is reasonable that as it gains popularity it will enroach into the smartphone market. It will be interesting to see this quarters figures; I suspect Android will grow but so will Apple.
As pointed out, the more important metric is profitability; and currently Apple have that in bucket loads.
(not that Android is doing badly, but it is a bit further behind, say 18 months, than people tend to suggest)
