The keyword is upto 4g. Clear as day. And they're not in "trouble". They're about in as much trouble as they were when cr said the ipad overheats.
Chicken little scenario. It'll blow over in a week, and we'll have a new thing that is supposed to spell the end for Apple.
Did you actually read what this thread is about? They are already in trouble with regulators in Australia and it's likely other countries will follow.
Here's a page from Apple UK;
http://www.apple.com/uk/ipad/4g/
They've got 4G in the url and in big letters at the top of the page. Then tiny print at the bottom saying it might not actually have 4G in your country. Why are they even mentioning 4G on a UK page when the iPad they are selling will never provide a 4G service in the UK?
Who said anything about it being the end for Apple? They'll simply end up having to rewrite their marketing material the same as they have on numerous other occasions for making misleading claims. Maybe give some refunds as well.
