A new report has unveiled that the iPhone 4S launched on AT&T actually supports 4G, a fact that had not been revealed by the company.

It has been revealed that when the iPhone was updated to iOS 5.1 from Apple. It was noted to be a 4G model, instead of 3G. And, it is being suspected that the company had misled people who do not have much knowledge about technicalities.

As per the findings of the report, AT&T and T-Mobile kicked their efforts of marketing the product by misleading public. They were allowed to bring iPhone in early years, while rival Verizon was made to wait for a period of three long years for the same.

Though the AT&T iPhone has been found to be a 4G phone, it is being said that 4G is truly only limited to WiMAX and Long-term Evolution. It has been revealed that these are the only companies to launch 4G LTE networks. The report has uncovered that smaller Sprint Nextel would be merging with WiMAX flavor, which is going to be obsolete earlier as well as Clearwire which is also struggling.

Both of these to become obsolete are on their way to develop LTE networks, as claimed by the report. As per the findings of the report, LTE network is not supported by T-Mobile. Also, it has been unfolded that iPhones on both T-Mobile and AT&T have been enticing fair amount of eyeballs and the two are therefore advertising HSPA+ networks only as 4G data networks.

"We're not going to get into a debate in the industry of what is 4G and what isn't. We leave that to others to talk about" at the iPhone 4S unveiling", said Mac maker, as per the report.
