HTC have released an updated version of the HTC Sync for Android application. This release supports all HTC Android models, including the original Hero provided that it is running the Android 2.1 update.
The installer will update existing installations, including the HTC Driver which will be updated to version 3.0.0.005, as well as install Adobe AIR 2.5.1.17730:

HTC have released an updated version of the HTC Sync for Android application that provides support for all HTC Android devices running 2.1 or later of the Android operating system, including the Hero, Legend, Desire and Wildfire.
This means you can now enjoy Windows Media Player and iTunes synchronisation on all of the above devices as well as synchronisation of pictures, documents and bookmarks with the desktop, not to mention synchronisation of contacts and calendar with Outlook.

The latest version of the HTC Sync application, version 3.0, supports all HTC Android devices running Android 2.1 or later and adds the ability to synchronise with iTunes on Windows, provided that you are running iTunes 9.2 or later.

Simply select Music and select which Playlists you wish to synchronise with the device.

The software update to Android 2.2, which began rolling out to European Desire users over the weekend, brings with it the ability to use the device as a portable WiFi hotspot: enabling you to share the Desire's connection to the Internet from any other device in range via a WiFi connection.

Setup is quick and simple, simply launch the WiFi Hotspot application from the launcher:

The Desire is HTC's latest Android offering, which they themselves have modestly dubbed a "SuperPhone" rather than a regular "SmartPhone", and even after only a few hours with the device I have to say it is worthy of the title.
Running the latest version of the Android operating system (version 2.1, or "Eclair"), the Desire packs a number of new features over older HTC Android models including an updated Exchange email client, support for Bluetooth file transfer, support for VPN connections, Version 3.1 of the WebKit browser as well as HTC's new "Friend Stream" social networking client. I will look at all of these features in more detail.

The HTC Desire and Legend units feature an updated HTC Exchange ActiveSync client, offering the same push-based bi-directional synchronisation offered by the Hero and the Tattoo, but now also offering the ability to set and edit Out of Office status and message as well as supporting remote device wipe from Exchange as well as the ability to enforce password usage via ActiveSync mailbox Policy.

Setting up the Exchange email account is very similar as on the Hero and Tattoo models.

The HTC Desire and Legend Android models feature the Bluetooth file transfer protocol, making it possible to wirelessly transfer files to and from your device from another Bluetooth-equipped device.

To enable Bluetooth on the device, browse to Settings --> Wireless & Networks:

Tick the option to Turn on Bluetooth.
Tap on the option for Bluetooth Settings:
