Taiwanese mobile phone maker HTC Corporation has made available a series of four new video promos with some of its high-end Android-based smartphones on the market.

The new video promos do not target only the recently launched high-end HTC Desire HD and Desire Z, but also the older popular smartphones HTC EVO 4G and DROID Incredible by HTC.

While the first two phones, which can be admired in the first video below, are set to land on shelves starting with the next month, the last two of them are already on sale in the United States via Sprint and Verizon Wireless, respectively.

Launched only a few weeks ago, the Desire HD and Desire Z are not new to the world, as the former is the European version of EVO 4G, while the latter is a flavor of T-Mobile G2, which should arrive at T-Mobile USA next week.

However, the two phones do come with a wide range of highly appealing features, including large touchscreen display, enhanced connectivity options, and powerful application processors.

Both HTC Desire HD and Desire Z are expected to arrive on the market starting with October, and various wireless carriers around the world already announced plans to add them to their offerings.

As for the HTC EVO 4G, which can be admired in the second video below, we should note that it is the first 4G-capable Android-based handset in the world.

Available for purchase at Sprint in the US, it comes with a large touchscreen display, and runs under the Android 2.2 Froyo flavor of Google's operating system, as it received the update last month.

The DROID Incredible is one of the most popular smartphones available in Verizon Wireless' offering.

The second high-end addition to the DROID family, the device has been updated top the new Android 2.2 Froyo OS too, and can offer a great deal of features to its users, just as the last two videos below (via Android Headlines) show.
