Probably in Ireland. It seems to me that (aka: I have no data) the vast majority of Irish use an iPhone.
The carriers have iPhones at roughly the same price as a half-decent Android phone, and those that can't afford to do that, get them second hand (usually older models..).
I have an Android, and I know several techie friends with Androids, but "normal people" have iPhones.
Really - It's almost a surprise to see someone with an Android here..
