In response to Steve Jobs statement that other phones on the market have similar antenna attenuation issues. Nokia and RIM said they "do NOT" have such issues as their phones are properly designed.
Nokia has clearly espoused that they "prioritize" antenna design for utmost reception at all times. But, how come they forgot severe signal degradation some E71?
Antenna design is a complex subject and has been a core competence at Nokia for decades, across hundreds of phone models. Nokia was the pioneer in internal antennas; Nokia 8810, launched in 1998, was the first commercial phone with this feature.
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're ever in conflict.
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 phones to ensure acceptable performance in all real life cases, for e.g. when the phone is held in either hand.

Apple's attempt to draw RIM into Apple's self-made debacle is unacceptable. Apple's claims about RIM products appear to be deliberate attempts to distort public's understanding of an antenna design issue and to deflect attention from Apple's difficult situation. RIM is a global leader in antenna design and has been successfully designing industry-leading wireless data products with efficient and effective radio performance for over 20 years. During that time, RIM has avoided designs like the one Apple used in iPhone 4 and instead has used innovative designs which reduce the risk for dropped calls, especially in areas of lower coverage. One thing is for certain, RIM's customers don't need to use a case for their BlackBerry smartphone to maintain proper connectivity. Apple clearly made certain design decisions and it should take responsibility for these decisions rather than trying to draw RIM and others into a situation that relates specifically to Apple."
