Hi everyone. I'm a newbie to the HTC Flyer (32gb, 3G + Wifi): I've had it for only a week, and love it (with Honeycomb update, etc.). I live in Ireland and have no need to add a SIM card here, because of regular WiFi access. But I'm visiting London for a few days soon and should like to use 3G mobile internet with the Flyer while I'm there. Can any Flyer users please recommend a pay-as-you-go type of SIM card that will work well with the Flyer in London but not commit me to paying much (since I'll only be in the UK for only a few days)? Or one that I can top up on later visits to the UK? I visit maybe 3 times per year.
