Starting today and on to the next three weeks or so, Sprint will be pushing out to Nexus S 4G users a software update intended to improve 4G data speeds and update the network signal strength indicators on the device.

The update also includes improvements to Wi-Fi connectivity, audio quality of speakerphone sound, and teletype (TTY) support for those who are deaf and hard of hearing. The update also enables the secure element of the Near Field Communication (NFC) chip on the handset, as well as fixes error code 67 when account changes are made.

Users will be receiving notifications from Sprint informing the users of the availability of software update version GRJ90 for their phones. Sprint encourages installing the update through Wi-Fi rather than over the air, as the file size is presumably large.

Sprint took steps to ensure that the update will perform excellently. The carrier sought feedback from some of its customers, as well as coordinated with Google and Samsung, which manufactures the Nexus S 4G, in order to figure out solutions for improving the device’s performance.

The Nexus S 4G is the only handset in the Nexus series that provides 4G capability, along with a pure and unadulterated Google experience with the fastest version of Android for smartphones, Android 2.3 Gingerbread.

Have you received this latest update? How satisfying is your experience of the Nexus S 4G on Sprint?
