The problem with Orange is: they don't have an EDGE network. Their 3G network is quite spotty. Once you're outside their 3G coverage, you can kiss surfing with your iPhone good-bye. I'd think they'll offer a real data flat simply because they know that nobody can use up more than 1gb per month anyway on their network - because half of the time people will be surfing at 9.6kb/s...
