Sprint has released the long-awaited Android 2.1 OS firmware update for the HTC Hero phone, along with a warning for HTC handset owners.
The mobile service provider advised Hero owners to make back-ups of their data before installing the update, as everything that is stored on the smartphone at the time of the installation will be deleted.
The company said: “You will lose contacts that have not been synced to an email account, text messages that have not been forwarded, saved voice mail messages older than 5 days, voice mails older than 20 days that have not been listened to, and call history.”
Sprint also advised users to remove the phone's MicroSD memory card before they apply the firmware update, as the Hero stores all its data on the memory card.
Users can download the firmware update for Hero from the Sprint support website. Once downloaded it can be installed on the smartphone via a USB cable.
