Sony's trio of new handsets is almost complete
The Sony Xperia P will give you a 1GHz dual-core processor, 4-inch display, Android 2.3 (Ice Cream Sandwich coming later in the year), 8MP camera with HD video recording, 16GB of internal storage and NFC technology bundled with a few of Sony's NFC SmartTags.
If you're on a tighter budget then you may want to opt for the Xperia U which features a 1GHz processor, 3.5-inch display, 512MB RAM, 4GB internal storage, Android 2.3 (Ice Cream Sandwich coming a few months later too), a 5MP camera capable of taking 3D images and 720p video and 3D surround sound audio technology.
