Nokia's new Windows Phone 8 handset, the Lumia 620, goes on pre-order

Online retailer Unlocked Mobiles has put the SIM-free Nokia Lumia 620 Windows Phone 8 smartphone on pre-order for £175, around 20 per cent less than the next cheapest WP8 device, HTC’s Windows Phone 8S, with which it shares a number of similarities. The first stocks are expected in a few weeks' time.

The Lumia 620 is the direct successor to the Lumia 610 (which can now be had for around £70 refurbished). It comes with a 3.8in, 800 x 480 pixel ClearBlack display, a dual-core Qualcomm Snapdragon system-on-a-chip clocked at 1GHz, 512MB of RAM, 8GB of on-board storage, a microSD caard slot, a 1,300mAh battery, a 5-megapixel rear camera with HD video recording, NFC, microUSB 2.0, interchangeable shells and of course Wi-Fi connectivity.

It runs on Windows Phone 8, which means that users can expect the same level of sophistication from a software perspective. It will be interesting to see whether Nokia launches a Lumia 720 given that the Lumia 620 costs half the price of the Lumia 820 (and a third that of the Nokia Lumia 920), which means that there is enough space for a mid-range model.

At £175, the Lumia 620 compares very well with chepaer Android smartphones such as the Sony Xperia Go and is a refreshing change from the significant premium the first batch of Windows Phone 8 handsets carried.
