The Desire Z and Desire HD are HTC’s latest smartphones to incorporate the new Google Android 2.2 (Froyo) mobile operating system. Both were announced last month and were recently made available in stores. VR-Zone managed to get both phones in for this review. Read on.

The HTC Desire was first announced in February this year at the Mobile World Congress in Barcelona. While it resembles the Google Nexus One, which was made by HTC too, the Desire has lots of differences including the HTC Sense user interface. The smartphone also received favorable reviews and that is probably the reason why HTC decided to come up with two new models based on the Desire series – HTC Desire Z and Desire HD.

The Desire Z features a slower 800MHz processor, while the Desire HD incoporates the second generation ‘Snapdragon’ 1GHz processor yet promises longer talk time and standby time. Both the Desire Z and Desire HD are running the new Android 2.2 (Froyo) mobile operating system.

So what are the added features offered by Android 2.2 as compared to Android 2.1? Besides improved performance, the newer version supports USB tethering, Wi-Fi hotspot functionality and installing of applications to expandable memory.
