The HTC Desire Z is currently the best selling SIM free smarpthone on Amazon for a good reason, it is their cheapest big brand Android handset and is available for only £265 including delivery.
The device, which was introduced back in September 2010, is essentially a classic Desire with a slide out keyboard with four rows of keys; it adds to the weight but this additional feature is worth it.
This means that you will get a Qualcomm Snapdragon SoC clocked at 800MHz, 512MB RAM, a 3.7-inch touchscreen WVGA screen, a five-megapixel camera with AF and flash and 720p HD video recording, microSD card reader, Free Sat Nav, Wi-Fi, GPS and Android 2.2 Froyo.
It also means you will be able to access Flash websites, lock and trace your phone remotely using HTC Sense or use it as a Wi-Fi hotspot.
Amazon even allows you to knock off another £50 from the price of the handset by joining their AudibleListener Plan with Audible.co.uk which is a subscription to their audiobook service.
The sudden drop in price may well mean that HTC will be releasing a slot-in replacement for the HTC Desire Z over the next few months.
It is likely though that before then, HTC will be upgrading the OS to Android 2.3.3 Gingerbread with a new HTC Sense user interface.
