First of all sorry to dig out old thread.
I'm quite new in FW patching for SE and having looked around on various forums I have a question on the flight mode patch.
Does it really turn the GSM module down (i.e. usable in actual planes) or is it just blocking all incoming/outgoing calls?
I understand that the network indicator is no longer refreshed when mode is activated but looking at GSM status in techmode I would have expected a blank screen.
Any idea?

If this matters I patched a K750 R1DB001 (hence the thread dig out:p) CID36
