Can't say that it's anything new, but AT&T has re-released the "new and improved" version of OS 184.108.40.2067 after pulling it earlier in the month due to call quality issues. Those that downloaded 220.127.116.117 prior to it being pulled may want to re-install it, as it appears that the Software Platform has changed from 18.104.22.168 to 22.214.171.124 (as seen in the picture above). New features such as Visual Voicemail are back, and call quality is said to be "improved."
Those that opt to download the new OS, please let us know what you think via the comments section! OS 126.96.36.1997 can be downloaded here.
