Whether ridiculous or not I think it virtually impossible that the prototyping in a different case obscured the issue. The RF engineers would have been fully involved with the case designers - from an antenna placement and construction point of view - from the very beginning. Presumably they are vaguely competent and are aware of both attenuation and detuning so I can only assume that they thought they had solved the problem in some way. Just as there were prototype iPhone 4s in 3GS cases the I would have thought it extremely likely that there were 3GSs in iPhone 4 cases to test the real antenna design. Eventually we'll find out what really went wrong and no doubt it will be something really stupid. -- Bruce Horrocks Surrey England (bruce at scorecrow dot com)

That's my hope too, but to be honest it's quite a distant one. Just tried again in our low-signal office: my 3GS showing three bars and Edge. Less than a minute of me holding the 4 reduced it to searching for a connection. That's not algorithm, that's physical. Would love to think it's manufacturing, but I'll need to hear of an actual change identified before I consider a change. To me, it looks like another year of 3GS ownership so far. No problem with that, is a good phone and I'll be out of contract in December so can go for cheaper deals instead. > > I wonder whether the iPhone 4 will end up being viewed by history as a > mistake, like the third-gen iPod with the touch-sensitive buttons > above > the wheel. I had one of those, and it wasn't a great design... Yep, I seem to remember coming out against those on this group too. Must say the physical look of the 4 doesn't appeal to me as much either: I prefer the literal shininess of the 3GS over the matt of the 4, and I prefer the curve over the slab. Ah well, we'll see. Cheers, Ian

A friend on Facebook has just told me he doesn't get the issue. Unfortunately he's halfway across the country so I can't get my known-to-cause-the-issue hands on it, but I've asked him to try a few things. I'll report back if he has anything interesting to say. -z- -- email: nettid1 at fastmail dot fm

That's not algorithm, that's physical. It could still be software. Not the algorithm that displays the bars, but the driver being unable to adapt to a change in signal. The iPhone 4 has some whiz-bang new software (in the baseband, or something?) which allows it to better select the best signal available - I think it more deeply monitors the strength of nearby frequencies. Perhaps there's a nasty bug in this, and it's simply not doing what it should. I have my doubts on this, though; if it was a software fix I'd expect Apple to have announced that rather than fobbing people off with a change to the way the bars are displayed. > Would love to think it's manufacturing, but I'll need to hear of an > actual change identified before I consider a change.

My 3G is feeling a lot older and creakier now; I would like a bit more speed. I'll probably go for a 3GS off eBay unless I hear of a believable fix. >> >> I wonder whether the iPhone 4 will end up being viewed by history as > > a >> mistake, like the third-gen iPod with the touch-sensitive buttons >> above >> the wheel.

To me, both designs have decent aesthetics. The retina display is a huge draw for me, though - I've always thought the iPhone screen was a bit poor with small text. And the speed and camera are also draws over the 3GS. -z- -- email: nettid1 at fastmail dot fm

Which implies to me that this is a manufacturing issue rather than a design issue. I guess it just depends on exactly how morbidly obsessed Apple is with secrecy. > Just as there were prototype iPhone 4s in 3GS cases the I would have > thought it extremely likely that there were 3GSs in iPhone 4 cases to > test the real antenna design. 3GS internals take more space than 4 internals. The "fake" 3GS case was just dummy plastic to pad the 4 out to 3GS size and shape. Retrofitting a 4-style antenna onto 3GS guts would be a lot more work (I'm not saying they didn't do it, mind). > Eventually we'll find out what really went wrong and no doubt it will > be something really stupid.
