That's funny because to me, in corporatespeak, saying it's "more" and not attaching a number or range to it might mean "significantly more" but they don't want people freaking out about it (which they will anyway, Apple's stock is going to take a big hit over this tomorrow).
It seems to me that they were originally saying under 1%, meaning they were confident it was under 1%, but they're no longer confident it is under 1%, so they're saying it may be a bit over 1%. I don't expect it to be, say, more than 5%, because at that point describing it as "more than 1%" sounds quite misleading.
