Last year, when Apple has announced its next-generation iPhone 4S in the public without any new design changes, and the adoption of the HSPA+ network instead of 4G LTE technology. We have heard that Apple and AT&T had been working together on the secret iOS 5.0 builds that allow both companies to bring 4G LTE technology on the iPhone 4S with a simple mask changing of the 3G network icon to the 4G icon, whenever the device is available under the HSPA+ strong signals, and able to use the maximum range of HSPA+ network.
It is reported that both AT&T and Apple had been working together to update the AT&T network indicator on the AT&T iPhone 4S devices, and allow the iPhone 4S devices to read the HSPA+ signals as “4G” in the device status bar whenever the device is connected to any HSPA+ network. However, that moment we had no confirmation and any clue about the reported feature arrival but now after the official launch of iOS 5.1. We come to know that both Apple & AT&T actually working on the project that was highlighted in the past by the internal sources, and the users now are able to get the “4G” indicator on their iPhone 4S whenever they connected with a HSPA+ network from their iPhone 4S.
A user posted a simple image of its iPhone 4S showing the 4G indicator on its status bar after updating its device to the latest released iOS 5.1 for the iPhone, iPad and iPod Touch. The above-mentioned screenshot clearly shows the indicator masking of the 4G in the iPhone 4S. Apple has today released the iOS 5.1 for the iPhone, iPad and iPod Touch devices on the iPad 3 launch media event with some bug fixes and the support of Japanese language for Siri.
