It's just marketing.

It's probably true that every manufacturer probably has more or less the same reception problems, but as the current king of the hill (at least in US), Apple has been taking hit in the media. And apparently it seems, that they still aren't used to being the cover girl of the month. They did everything they could in the press event, blaming others, giving free bumper cases and money-back-quarantee. Does it help? Probably not, as the problem is still there. And the press is greedy.

And Nokia? Well... who is willing to test all the models in the market? Globally? It's true that Nokia has way too many model numbers, but in this case it's actually an advantage. It's pretty safe IMHO for them to publish a statement like they did today.

Other manufacturers will follow, RIM in the first place. It's going to be interesting!
