Sun Unleashes Biggest Flare of the Current Cycle
On February 13, 2011, sunspot 1158 let loose the strongest solar flare of the current solar cycle, a blast of radiation across the electromagnetic spectrum, from radio waves to x-rays and gamma-rays. NASA’s Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation, as seen above, and located in approximately the middle of the Sun’s disk in the image below. The eruption also produced a loud blast of radio waves, and coronagraph data from STEREO-A and SOHO agree that the explosion produced a fast but not particularly bright coronal mass ejection. Spaceweather.com predicts a CME cloud will likely hit Earth’s magnetic field on or about Feb. 15th, and high-latitude sky watchers should be alert for auroras.

The scientists expect the flare to effect the earth for two days or three, 16th to 17th or 18th. They suspect that the high-energy particles might damage satelites' communication related critical parts.
2012 is just a theory, but hey... who knows...
If you wish to learn more about suspected side effect, search for "GPS-denied navigation".
Updated:
HF radio signal was effected, and currently has no problem. Please keep in mind that HF signal can be disrupted unexpectidly.
It is expected that consumer radio items, such as cell phone and other mobile TV systems (DMB) will also be disrupted, with occational signal drop and/or disconnection. Dispruption duration is expected to be 1~3 seconds with unknown waves. Satelite TV system users should expect abnormal screens.
