I got my iPhone 4 delivered a week ago. It spent three days without a case. I made dozens of phone calls to my friends and intentionally tried to replicate the signal drop issue. I couldn't. I know of three others who bought the phone, and they haven't been able to replicate the issue either. Whatever the cause is, it is not affecting everyone.
It could possibly be an issue with phones that came off the first run. Perhaps they were not put together with as much care or attention. (Remember the still-wet bonding agent that caused the yellow discoloration?) Some have been able to fix the issue by simply re-seating the SIM card.
In fact, this isn't the only phone having an issue of this sort. There is a flaw in the Droid Eris that prohibited someone from contacting 911 at the scene of an automobile accident. I fail to see the same level of attention and objectivity being reported by the same sites that are cannibalizing Apple.
This is not an issue with faulty brakes on automobile. This is not an issue with a child's toy produced with deadly, toxic materials. This is not an issue where the phone needs to be rebooted to regain functionality. This is an issue with a phone, when held in a certain way, loses a call, and it is an issue that is solved by either moving a finger, purchasing a case, or insisting upon an exchange (as not all units are affected) or a refund.
Yes, it is a design flaw, but at the end of the day it is an inconvenience. An example of an Apple design flaw that was much more than an inconvenience was the 800 MHz G3 iBook (my first Apple purchase, incidentally). The GPU was shoddily soldered onto the underside of the logic board and would lose its connection with the socket, rendering the laptop unusable. That was an inexcusable design flaw, and even that Apple offered a free extended warranty to anyone who had purchased that model, much like they're doing with a series of Time Capsules that have been experiencing trouble.
I don't understand why everyone wants to destroy Apple (and by proxy Steve Jobs) over this issue. Is it because they "have it coming"? Is it because they "deserve it"? They introduced a product with a design defect, an inconvenient one at most, and it makes headlines as if the world as we know it is coming to an end. Buy a case, exchange the phone or demand a refund.
I know I'm either going to be labeled a fanboy, troll, or have responses stating "that's not the point", but I really don't care. The overreaction to a simple design flaw is climbing to hysterical levels. I don't care if he really said it or not, but I'm going to have to quote "Steve Jobs" and say:
It's just a phone.
