4G, or 4th Generation Mobile standard, uses high speed networks that have to meet certain criteria such as a download speed of 100Mb a second for someone on the move and 1Gb a second for an immobile location or someone who moves at a slow speed. The Evo, an Android-based phone released in 2010, was the first 4G phone. IPhone 5, which was released in 2012, was the first iPhone with 4G connectivity.
