 UMTS capable SIM, Dutch KPN, got it last autumn.
 upgraded firmware to moko11
 FSO milestone 5.1

 Zhone, starts fine, detects SIM, asks for PIN, delivers it, gets
 registered and then after a varying amount of time, claims to be
 deregistered. The Neo can still receive calls. The bottom-left
 icon/program still lists an active cell and show changing activity for all
 cells it can detect. I can even make a call from the command line.

 switched on logging, found the following:
 2009.02.24 19:50:15 ogsmd.channel DEBUG    <MiscChannel via /dev/pts/0>:
 COMPLETED 'AT+COPS=3,0;+COPS?;+COPS=3,2;+COPS?' => ['+COPS: 0,0,"NL KPN
 "', '+COPS: 0,2,"20408"', 'OK']
 2009.02.24 19:50:15 ogsmd.channel DEBUG    <MiscChannel via /dev/pts/0>:
 COMPLETED 'AT+COPS=3,0;+COPS?;+COPS=3,2;+COPS?' => ['+COPS: 0', '+COPS:
 0,2,"20408"', 'OK']

 and as otimed says, there's no network code in there. As a consequence,
 Zhone claims the SIM deregistered and disables the phone icon.

 This can happen (as in the example) virtually immediately, or any amount
 of actions later. call, answer, look at cell(s), do another call and oops-
 there's the COPS result. Whenever the phone icon gets disabled, there is
 the COPS result without provider; and there's no other COPS result without
 it earlier in the logfile. Later results of the COPS command do not have
 the provider, either. Restarting X+Zhone seems no different from rebooting
 the Neo.

 firmware bug or zhone bug?
