errors using mdbus commands

[Steve " 'dillo" Okay]

I'm having some problems with getting dbus GSM commands working from  
the command-line:

root at om-gta02: # mdbus -s org.freesmartphone.ogsmd /org/ 
freesmartphone/GSM/Device org.freesmartphone.GSM.Device
.GetInfo
/org/freesmartphone/GSM/Device: GetInfo failed:  
org.freedesktop.DBus.Error.NoReply

root at om-gta02: # mdbus -s org.freesmartphone.ogsmd /org/ 
freesmartphone/GSM/Device org.freesmartphone.GSM.PDP.Ge
tNetworkStatus
/org/freesmartphone/GSM/Device: GetNetworkStatus failed:  
org.freedesktop.DBus.Error.NoReply
root at om-gta02: #

I'm running FSO 5:
root§om-gta02:ß# uname -a
Linux om-gta02 2.6.29-rc2 #1 PREEMPT Wed Feb 25 16:01:57 CET 2009  
armv4tl unknown
root§om-gta02:ß#

 From reading the mailing list archives and the Wiki, it's not  
entirely clear to me if this is an invocation error on my part or an  
actual bug.
Do I have to allocate the GSM resource via org.freesmartphone.ousaged  
first ?
It seems like I should be able to do a GSM.Device.GetInfo from the  
command-line based on what I've read so far.
Have any of the object pathnames changed between FSO 3 and 5 ? The  
examples on the Wiki say they're for FSO 3.

Any thoughts/help/thwacks on the head would be appreciated.
Thanks,
----Steve
