The latest operating system for Apple, iOS 5.1 is now available and apart from delivering a new camera shortcut, Japanese for Siri and a new camera app for the iPad, it appears something else has arrive with iOS 5.1 just for the AT&T iPhone 4S.
The iPhone 4S has an HSPA radio that can reach theoretical peak download speeds of 14.4Mbps. From a marketing standpoint, AT&T has the right to market the smartphone as a 4G device. But technically, the iPhone 4S does not meet the minimum requirements for being a true 4G smartphone, namely having an HSPA+ radio reaching speeds of at least 21Mbps, or having LTE or WiMAX connectivity. Note that the newly announced iPad is available in LTE flavor, which makes it a proper 4G tablet.
A redesigned antenna that allows for faster HSDPA connections is one of the major features of the new iPhone 4S that debuted last October. However, at the company's keynote presentation, Apple executives did not outright declare that the iPhone 4S is a 4G phone.
U.S. carriers AT&T and T-Mobile have advertised their own HSPA+ networks as having "4G" speeds, even though they aren't true fourth-generation technology. AT&T is currently rolling out a true LTE 4G network in the U.S., and is available about 75 million people, while Verizon's LTE network reaches over 200 million people.
