OK, well, clearly you can't please all of the people all of the time. I understand where you guys are coming from and respect your points. I appreciate you taking the time to comment. The headline was only meant to suggest that the antenna has what had been a problem spot on the CDMA version in the same location. We can't tell the full story in the headline. Those of you that found the article useful and interesting even if you didn't agree with the headline, that's usually good enough for me. Thanks again everyone. We value the feedback.
I suppose you could strangle any cell phone if you were so inclined.
But given the capability of these phones, if the phone itself chatted with you during a signal loss you probably wouldn't notice the difference.
(wacky - wacky post)
I think the general consensus is that the article itself is fine, but the headline is inappropriate. The article does not offer anything to support the implied claim of the title that the phone suffers from the death grip defect of the previous GSM design.
I was one of the gents that was involved in the teardown of the iPhone 4. I think the wording of the article may have caused some confusion to you so here is my take:
The "death grip" antenna is still in the same location. If that was the only antenna change, the issue with dropped calls would most likely reoccur.
HOWEVER, the addition of the Diversity Rx antenna by it's very definition improves the quality of the reception. Whether or not Apple intended for this is what we don't know. My understanding (and I could be wrong here because by no means am I an antenna expert), because this is a CDMA phone, designers typically choose diverity receiving as a default.
My opinion is that Apple knew the reception was going to be improved regardless because this was a CDMA phone, so a drastic redesign of the antennae was unnecessary.
Though I am hearing rumors that in areas of questionable coverage, where the benefits of diversity Rx aren't possible, the death grip is causing dropped calls. I cannot confirm that though.
After the issue Apple had with the GSM version, I would be very surpised if they didn't do in depth testing before releasing the CDMA version. So the test data exists within Apple. It would be interesting to see independent test results, but I would expect the result to be acceptable.
The teardown images of the iPhone are a tremendous advance over previous articles in the media about the "death grip" problem that causes the iPhone to drop calls. However, as other readers have mentioned, the article seems self contradictory regarding the antenna redesign and design issues. PLEASE take the last step and show all of us how and why this antenna design suffers from problems when the phone is held a particular way.
The re-design seems to be a good one. The nice thing is that Apple doesn't need to change the outlook of the phone and people basically won't aware of any change at all. Anyway, still would to like to wait for the field test result.
