Depends on how you want to do it, but I'd just get an unlocked one,
stick a PAYG SIM in it and see if you can live with it over an
extended period. Then switch or send it back. Again, it'll vary
depending on your sevrice provider, but with O2, for example, you just
fill in a web-form to transfer your remining contract to the new SIM.

Neither, if I heard what Jobs said correctly: it's an inherent
property of antennae; touch one in the right (or wrong) place and you
will detune it. How much depends on who's holding it, what signal
level you had to begin with, the phase of the moon &c.

Again, if I heard him correctly, it was a deliberate trade-off: yes,
they knew there would be a signal drop, but putting it outside the
case meant it pulled in more signal to start with. In most cases, the
improvement far offsets the signal drop when you hold it. A tiny
proportion of iPh4 owners (0.05% if his figures are to be belived) is
adversely affected, and he'll give them a full refund.

It's the usual "squeaky wheel" syndrome, isn't it? The ones who make
the most noise get the attention.

Yeah, that was a leap in the direction of "proper testing". Good old

Oooh, that may just have made me reconsider -if the worst-case data rate
is better than the best-case 3G data rate, then where's the problem?

I have to wonder how this will change in a poor signal area (rather than
the reasonable-but-not-great one they were in). Seems odd that they
couldn't kill the data completely - I'm wondering whether "No Signal"
death grips are harder to achieve once a data connection is made (just
as they are harder when a call is in progress).

Perhaps I will start agonising after all. Probably not, though...

If I bought a PAYG SIM I'd have to take it back even if the unit worked
for me. PAYG would cost a fortune. And then I'd be in the same position
that I was in before; just cos that unit worked for me doesn't mean that
a unit I buy on contract has any greater chance of working.

It seems like a lot of potential hassle for a very low chance of
success.

Or the quantity of text in each. But "agonising" implies I'm not
enjoying it. But I am; accuse me of wittering on if you want, but I'm
not agonising. It interests me.

I don't think I even agonised over whether I should get an iPhone 4;
when I found I triggered the problem without trying, I decided to wait
and see if it was widespread; when I found it was, I decided to wait and
see if a quick fix appeared; when it didn't I decided to stick with what
I had for a bit. Disappointing, but hardly agony.

Sorry, I don't understand. Some units neither suffer more or less than
others? Or are you saying all units suffer the same amount? I'm fairly
sure (now) that they do, but I don't know for sure. Even Apple haven't
confirmed this, and others that have said it's confirmed (Engadget),
have done so quite shoddily.

Gruber makes the point that Jobs never actually used the word
"trade-off", but should have.

Depending *how* you hold it. If you don't touch the spot, the signal is
better. If you do, the signal is worse. At least, according to the data
I have seen (and my personal experience). Have you seen something that
disagrees with that?

I'm sure that Apple knew that spot caused issues; I'm concerned that
they didn't notice that a large number of people will touch that spot
accidentally.

I wonder whether they only tested people making calls? This is a lot
less likely to involve touching the spot, and even if it does, touching
the spot during a call is a lot less likely to drop the call than
touching the spot outside a call will give "No Signal" (presumably due
to adaptive power negotiations between the cell tower and any phones
making a call through it).

Did they test people holding it while using apps? Did they notice that a
common natural grip causes loss of network connectivity? If not, why
not?

0.05% of Applecare users does not equate to 0.05% of users being
dissatisfied. What percentage of annoyed users don't have Applecare?
What percentage do, but don't call? It's an obfuscating figure, just
like the "one more call dropped per hundred", and does more to confuse
the issue (in Apple's favour) than it does to clarify.

It's exactly that problem that I am trying to get around. The noisy
people are distracting from the people who are trying to work this stuff
out properly.
