2G...
Yes one day I am sure 2G will go (as 1G [analogue] did).
At the moment though, 2G is still by far the widest network for basic call/sms access, covering 99.9 of the landmass - without it, you'd have no mobile access at all in a lot or areas, especially rural.
Also, it's a back up for when 3G is busy in your location, so if your call cannot be done on 3G, your phone will kick you back over to 2G.
When 4G is capable of carry calls/sms as well as data (I dont know if that has changed yet since I left the industry). Then of course, you'll have 3G/4G spectrums, so the need for 2G will gradually reduce.
I'd say by the time of this happening, the "basic" phones will be 3G capable anyway (more and more low end handsets (£30-80 range) are touch screen, data capable etc etc now) and should imagine this will only continue.
