I have the iPhone 4. I love it more than any other iPhone I've owned. Yes, it does drop calls very frequently when I use it without a bumper. No, it does not drop calls with a bumper. Do I still love it and use it? Yes. Is there a reception problem? Depends on who you talk to, I'd say there is an issue but it's livable and not the end of the world. Jobs is right, sometimes I'm just holding it wrong and the attenuation starts. Sure, it's a flaw, but I still love my phone, it works well enough for me to keep using it, and everybody wants to justify buying it with or without the design flaws.
Nobody was hurt during all this. The media and pissed off owners and non-owners need to give it a rest. And for the apple fanboys unlike me who have to lie and say no I've never had a dropped call without a case, well, you're not helping our case by stating what has statistically proven to be untrue by Apple.
Just another blindly ignorant post.... I have the iPhone 4, use it with no case and have NEVER dropped a call, even when purposely trying to touch the area. According to you then I must be lying...
