A software upgrade is available for HTC HD2 customers at www.t-mobile.com/wmupgrade. Please be aware that after you upgrade the phone It is normal for the device to run slowly and the battery to drain at a higher rate for a short period of time. This is caused by applications that might be performing an initial sync, such as, Outlook or a personal e-mail account, or the device updating applications like weather and location. It may take up to four hours to complete all syncing.Important: Please read the steps on How do I perform a device software upgrade before moving forward.
