 I have a 71234(O)/4022. This is the only non-ancient SIM card that works
 at all on the AT&T network in the USA. The network registration is spotty.
 At times the phone registers quickly at boot, at other times it doesn't at
 all. Sometimes a reboot makes it register. This is all without touching
 the SIM. This instability, in addition to the fact that the pins impact
 dead-center on the pads of the SIM makes me think that the wiggling of the
 SIM is a red herring. I'm including several runs of the diagnostic script.
 These were done one right after another, without moving or touching the
 SIM. After the first boot, the FR said "Registering..." the whole time,
 even though the logs indicate that registration was acquired at one point.
 Then I reboot, and the FR registered successfully. Several noteworthy
 points are that once registered, the logs indicate that the phone kept
 changing the network cell it was connected to. Also, one of the commands
 generates a number very similar but not exactly equal to the code of my
 SIM (something like 7 digits in a row match). I don't know if this is
 supposed to match my SIM code exactly or not.
