Windows Mobile 5 GSM "message from network" alert

I am playing with a nice new Symbol MC70 running Windows Mobile 5, and its pretty good but.........
With GPRS enabled I continuously get  a "Message from Network" alert popping up which I think is the cell broadcast info alert.

I have managed to stop it making a silly sound when this alert pops up, but is there any way of dsiabling the alert completely.

If the device goes into a power down state, I can have a number of these queued and have to clear them all down before I easily work with any application.

I have found details of a reg hack for the MSN messenger popup up alerts, which allows these to be blocked, but cannot find anything similar for the cell broadcast alerts.

If I put the SIM into a nmormal phone, it looks as if cell alerts and cell info messages are tunred off, but I suspect that this is the phone itself, and not details stored on the SIM ?

Any suggestions folks...........................................

This what symbol says

The message indicates that it roamed between networks or towers.
As cell broadcast messages are built into the MC70 and defined in Phase 2 of the GSM standard in GSM 03.49.

The following key can be used to turn off the cell broadcast feature of the MC70:

[HKEY_LOCAL_MACHINE\Software\Microsoft\RIL]
"EnableCBM"=dword:0
"EnableCBMChannels"=""
"EnableCBMDCS"=""

Goodluck

"Message from Network"

0175302001895 01784@

The first part I think is the 02 broadcast number, and 01784 is the cell area code.

If the device is on one location - left on a desk - then the messages stops
If I then move around the building, the messages restart, swapping 01784 to an 020 number and back

i think the only way is to get a SMS blocker with rules.

Maybe this one:

For example Block SMS's where Subject = "Message from Network"

Sorry, the SMS blocker does not pick it up - I think that this is because it comes in as a network alert, and not and SMS message into the phones inbox.
