Here you go (This is from a ATT Bold):
+COPS: 0,2,310410

OK

I am not going to be overseas until next year and with travel being
reduced here I may not get a chance to have someone test remotely
until then but here are the same commands for a Blackberry Storm.


Storm 9530:

ATi:

Manufacturer: Research In Motion
Model: 9530
Revision: OS Ver: 4.0.0.181  [May 13 2009 22:53:31]
ESN: 0x80986ECB
+GCAP: +CIS707-A, CIS-856, +MS, +ES, +DS, +FCLASS, CIS-856-A

AT+COPS=?

ERROR

AT+IMSI:

ERROR

AT+COPS?:

ERROR

The Storm seems to auto-detect the location you are in and Roams to
GSM automatically but I can't be sure what the changes are for that
since it wouldn't let me force it to Roam here.
