New NPD data has credited the iPhone 4S as the primary factor behind the adoption of 4G or pseudo-4Gon smartphones. Where just six percent of devices had support for HSPA+, LTE, or WiMAX at the end of 2010, about 35 percent had it during the newest iPhone's fall launch. Even though it only had two months to sell, Apple's hardware became the most popular HSPA+ phone in the US for all of 2011.
