One more point regarding the giffgaff changes: apparently the current roaming limit of 20GB will remain and will not increase at this time. I'll be testing this out in April when I buy a £20 Goodybag that I'll be using solely in Ireland--I think £20 (about $26 at the current exchange rate) is a good deal for 20GB of data. I'm not worried about the call and texting rates as I use Google Voice for those purposes.
