ROM upgrades, which often deliver important new features (such as platform updates), fixes and enhancements, are available for a variety of recent Windows Mobile smartphones. Whether you choose to upgrade will depend somewhat on your carrier and your device. Take a look at what the upgrade promises and then decide.
But, before beginning an upgrade, be sure to back-up your device.
