what everyone is lying about is "privacy" in GSM communications!
They were shocked to discover around one hundred and twenty-two incidents/anomalies consistent with many highly active, even dual-band, completely genuinely FAKE GSM base-stations in Norway!
People targeted included PM, MoD, Central Bank, parliament, Embassies, major businesses... potentially anyone with a GSM in Oslo; a spokesman from PST (Norway's MI5), Arne Christian Haugstøyl, came out with "we warn persons ... against discussing sensitive matters on the mobile phone"
I'd say that all of the no-doubt similarly illegal GSM systems in UK will be off for a few days, whilst this storm blows-over, unless the Daily-Mail picks up on it. Aftenposten couldn't get any comment from their BT equivalent. Is it a good time to invest in EE? - well maybe if A5/3 gets a roll-out in UK, (that would be a stop-gap solution to have a partially secure algo whilst GSM is buried and the spectrum refarmed for 900MHz LTE)
