The budget Sony Xperia J has been unleashed on parts of the world. Specifically you can buy it right now in the UK, Russia, Hong Kong and India.

We brought you news of the release back in August, but we’ve learned more about it since then. It is sporting a 4-inch touchscreen with an 854×480 pixel resolution; it’s got a 1GHz single-core Qualcomm processor, 512MB of RAM and it’s running Android 4.0 (ICS). It also has a 5MP camera with LED flash and there’s a microSD card slot, which is just as well because there’s only 4GB of storage. It also has a nice big 1,750mAh battery and a front-facing VGA camera.

The specs aren’t going to blow you away, but it’s a nice-looking phone and it comes in black, white, pink or gold. The obvious attraction is price. This is an entry-level device which you can pick up in the UK for £170 on a pay-as-you-go contract at O2 or you can get a SIM-free version direct from Sony for just £219.

In Hong Kong it is selling for HK$2,098, in India it will cost you INR 16,490, and in Russia it will be around 11,000 Rubels. It will be rolling out elsewhere in the very near future.

It also supports Wi-Fi, Bluetooth, aGPS, DLNA and it has a Walkman app and Facebook and Twitter integration. Network-wise it’s GSM GPRS/EDGE and HSPA. What do you think? Is the Sony Xperia J a good bargain? We think it is.
