The HTC Cingular 8525 was originally installed with Windows Mobile 5.0, however a ROM update to Windows Mobile 6.0 eventually arrived through the official HTC website. While that ROM is no longer officially available through HTC there are still ways to obtain the official ROM. Once downloaded you can then update your device using the pre-installed Windows Mobile Device Center found on your Windows Vista operating system.
