Technically it refers to a family of standards for mobile telecommunications as defined by the International Telecommunication Union which includes GSM, EDGE, UMTS, and CDMA as well as DECT and WiMax. Services include wide-area wireless voice telephone, video calls, and  wireless data. Compared to second-generation services, 3G allows simultaneous use of speech and data services and higher data transfer rates.

Even though it refers to third-generation technology, online slang has morphed the usage into something that is so happening, so right now, as in "Have you seen Dillon's iPhone yet? It is so 3G."
