iPhone 4 Rival Alert : Nokia Lumia 710 Goes On Sale At Vodafone

Vodafone has announced that the Nokia Lumia 710, the most affordable Windows Phone Mango handset on the market, is now available on PAYG or Pay Monthly plans.

Both O2 and Three already offer the mainstream device on PAYG for £210, while Vodafone is rumoured to be selling the smartphone for just £150.

Although it is cheaper than the Lumia 800, it has inherited many of the features of its bigger brother, like the 1.4GHz single core Qualcomm Snapdragon processor, the MSM8255T, that lies at its heart.

There's a five megapixel camera with flash, 512MB RAM, 8GB onboard storage, a free satnav service called Nokia Drive, Nokia Maps, Internet Explorer 9 plus Zune and Microsoft Office Mobile.

Vodafone sells it for £20.50 per month on a two year deal with 100 minutes, 500 texts, 250MB data allowance and 1GB BT Openzone Wi-Fi access.

Note that you will be able to get unlimited data for three months through Vodafone's test drive service.

Nokia is expected to launch a high end smartphone, possibly a Windows-based Lumia 910 model, at the Mobile World Congress event that will take place towards the end of the month in Barcelona.
