the solar pole reversal doesnt effect the earths poles, in fact the sun flips every 11 years, around the solar maximum, while this can cause problems with satellite communications its something we've lived with throughout the space age
the earths poles will also shift someday, but not in 2012, geomagnetic pole reversal is much less predictable, at the current rate of change in the earths magnetic field the poles will reverse sometime between the year 3000 and the year 4000
what effect this will have on our electronics is entirely unknown, but as a species it is unlikely to effect us, as human ancestors survived several pole reversals in the last few million years
heres an interesting article dealing with the last solar pole reversal, in 2001
