Having had my ipad for almost a month now, and experienced so-so service from O2 (good on one cell tower in London SW3, no so much on another with constantly having to reset 3G to restart service) plus the terrible image compression and lack of iplayer, i decided to try Orange today, not willing to risk the indian call centre of three and I think Vodafone is too expensive. Well, 8 hours in and I'm thrilled with Orange. No image compression, rock solid connection all day, iplayer works and it wasn't a dreadful fuss to set up either via the orange website which just worked after the APN had come over from iTunes. Obviously your mileage will vary in different areas, but this is great in London. Getting just under 2.3k in speedtest.net, by the way.
