Thanks Jack, Very useful.
FYI United States is missing from the list (but is on the website). I'm assuming from the website it's 4G with AT&T
Re the 10Mb charging block mentioned above - when I signed up this was mentioned in the T&Cs, however it now seems to have been removed... If so that would be great as it would enable people to use their phone as they do at home - ie. with email, facebook, twitter, whatsapp etc continuously syncing small amounts of data, and not create any negative user experiences as they see their data drained quickly.
However on testing the service, every time I have connected to Flexiroam, 10MB (shown as 0.01 GB) has been deducted, and when I spanned the end of an hour into a new hour 20MB was deducted. In all cases I had minimal actual data usage, which makes me think the 10MB block is still being deducted
