Slight thread drift.
I'm not really sure that newer is better.
Reference digital TV: When there is tropical storm activity in the local area two of the major networks become very intermittent with pixelisation of the video signal and clicking sound effects. It nearly blows my (expensive) surround sound system speakers apart.
Reference mobile phone reception: I used to regularly cancel SAR via mobile phone at 1500 ft in a very remote location in CDMA days. FA chance of doing that now with 3G.
Back to the original thread, sometimes whilst flying in remote areas my phone will report a service provider of 999 999 instead of Telstra in the service provider field. Does anyone know what this means? Free calls maybe??
