What an opppurtunistic attempt by Nokia to ridicule Apple since Steve Jobs said one need to hold the iPhone4 correctly to have good reception. Read the article - I reproduced the last 3 paragraphs here. I like their last closing paragraph - the killer comment ( highlighted in bold )
We’ve found any of the four grips mentioned above to be both comfortable and as you can see, offer no signal degradation whatsoever. This isn’t a feature you’ll only find on high-end Nokia devices either. It’s something that’s been a part of pretty much every Nokia device ever made (perhaps with the exception of that teardrop 3G one, which was a bit ridiculous).
The key function on any Nokia device is its ability to make phone calls. After all, that’s why we know them universally as mobile phones (or smart phones, feature phones or mobile computers – though the same grip styles work for those, too). One of the main things we’ve found about the 1 billion plus Nokia devices that are in use today is that when making a phone call, people generally tend to hold their phone like a…. well, like a phone. Providing a wide range of methods and grips for people to hold their phones, without interfering with the antennae, has been an essential feature of every device Nokia has built.
Of course, feel free to ignore all of the above because realistically, you’re free to hold your Nokia device any way you like. And you won’t suffer any signal loss. Cool, huh?
