The HTC ChaCha was launched last year at Mobile World Congress in an apparent move by HTC to attract the attention of Facebook users, but it seems that adding a dedicated blue button to the phone was not enough.

Not surprisingly then, the phone is being sold on Argos' eBay outlet for only £90 including delivery, a fraction of the price it used to command at launch. It is locked to 3's network and you can get the Vodafone version for £4 extra.

The handset comes with a Qualcomm MSM7227 processor clocked at 800MHz, 512MB of RAM, a four-row QWERTY keyboard with a dedicated Facebook button, a microSD card slot (a 2GB card is included), a rear 5-megapixel camera, a front-facing one, and Android 2.3 Gingerbread with HTC's Sense 2.1 user interface,

Completing the feature-set is a micro-USB port, a 1,250mAh battery with up to 420 minutes talk time in 3G, and a 2.6in 480 x 320 resolution capacitive touchscreen display with Gorilla Glass.

At 15mm thick and weighing less than 100g, the ChaCha is not unlike an entry-level Blackberry smartphone (like the Curve 8520) although one may argue that the ChaCha packs significantly more value for money.
