Yes, it is. AT&T is trying to cut back on the data network usage in the US, because their network is so bad (no, it's not the fastest 3G network available).
Yes. It is also true here in the US. AT&T is offering two options. I believe it's 500mb for $15 a month and 2gb for $20 a month. I think it's outrageously dumb. AT&T just needs to admit that their network sucks and fix the problem. A phone is good as the iPhone deserves better service than that. Just my opinion.
yeah its true. i talked to the att operator yesterday and she said the reason they took it away is because no one was going 2gb of data. and instead of having all of the complaints of customers with the unlimited data plan, they just took it away completely. it makes sense because if no one ever goes over 2gb, then they will stop all of the complaining and have more happier customers.
