"Sprint and HTC regret any inconvenience customers have recently experienced with the Mogul. HTC is working on a new version of the software ROM for the Mogul which incorporates enhancements for Bluetooth performance and corrects issues that were unintentionally created by ROM version 2.16.651.0 (posted on HTC’s website on October 24). Both Sprint and HTC have begun testing the new software and are targeting to make it available for download by the end of November. Once fully tested the download will be made available on this webpage. Please bookmark this page for easy reference."
