Earlier today in the Apple Press Conference Steve Jobs made much of the fact that signal degradation issues based on grip were common in other smartphones, including Nokia devices. The titanic phone-maker has already issued a press release addressing this perceived slight.
"Nokia has invested thousands of man hours in studying human behavior, including how people hold their phones for calls, music playing, web browsing and so on. As you would expect from a company focused on connecting people, we prioritize antenna performance over physical design if they are ever in conflict."
It's hard to take that last bit as anything but a direct jab at Apple. The release went on to twist the knife even deeper;
"In general, antenna performance of a mobile device/phone may be affected with a tight grip, depending on how the device is held. That's why Nokia designs our phones to ensure acceptable performance in all real life cases, for example when the phone is held in either hand."
Sorry Apple, but you had that one coming.
