The update is, we're still on it (I posted some days ago).
And, like Matt says: It's depending on Provider (plus a plethora of other 
factors), but doesn't seem to be very device-specific (i.e. changing your 
device for a new one doesn't help, at least right now). Changing Provider may 
help a lot.
Seems, this (GSM-noise) can't be tackled by asla setup. Though low volume, 
echo etc actually can, to a certain degree.
