Disabling Cell Broadcast on the MC70

There appears to be a 'fault' on the Symbol MC70 where when you setup a GSM connection on the device, the OS will decide to incessantly alert you the current cell the device is connected. Suffice to say, this gets very old very quickly. Apparently this is not the default behaviour, however there is a workaround.

Setting the following registry key on the device will disable these messages:

[HKEY_LOCAL_MACHINE\Software\Microsoft\RIL]
"EnableCBM"=dword:0 ;## enable/disable : 1/0

And don't forget to do a soft reset on the device so it picks up the new registry value.

Even better, what you can do on on your app's CAB installer is configure it so this registry key is set up every time you deploy your app to a new device:












Voila! This way you don't even need to think about it.
