i was able to cause it to change by holding it wrong.

nobody holds a cellphone with a single finger so that's entirely moot.
i held it normally, like anyone would hold a cellphone.

a *lot* of phones require special procedures:

Update: I've now seen some change. Where I am right now the phone
shows -89 dBm lying on the table. When I hold it (in either hand), it
drops to -101 dBm. That appears to be the next possible value -- I've
never seen an intermediate value. But there is no change depending on
how I hold it (either hand) -- the usual value here is -101 dBm,
sometimes jumping to -89 dBm or -109 dBm before returning to -101 dBm.
This is on GSM ("E"GPRS indicated), not 3G, which may have been what
I was measuring before.

that's quite a drop to go unnoticed in your 'careful testing.'

Cool. Finally some real numbers instead of useless number of bars.
For those that want to play with numbers instead of bars, go into the
"test mode" as documented here:
<http://forum.thinkpads.com/viewtopic.php?f=27&t=84953>

That's a 12dB drop in signal level, which is signifigant, but nothing
compared to the 24dB drop observed with the iPhone 4. Note that the
signal level is half for every 3dB drop.
