Although it hasn't exactly been kept a secret, we're all very excited to announce that the new 3 Skypephone is here. It's called the S2, and as with the first 3 Skypephone, Skype is fully integrated, so you can make and calls and send instant messages to Skype users anywhere in the world absolutely free.

Equally, it's absolutely free for other people to call you or message you on Skype while you're using the 3 Skypephone S2. Of course, it does all of the other things you'd expect a mobile to do too - make calls, send text messages, take photos and browse the web.

How does the S2 compare to the the original 3 Skypephone?

New user interface — even easier to use than the original 3 Skypephone, with a carousel interface which makes switching apps speedy. It preserves the integrated Skype phonebook, so your contacts' Skype names appear alongside their landline or mobile phone numbers.

Better build, screen and camera — it has metal keys and back as well as a bigger screen (2.2" vs. 2") at higher resolution (240 x 320 vs. 176 x 220) and a better camera (3.2 megapixel vs. 2 megapixel).

HSDPA broadband and built-in dongle capabilities - it has built in modem drivers so you can use the cable that comes in the box to plug it into your laptop and get online.

Facebook and Last.fm apps and RSS reader - convenient access to Facebook and Last.fm, plus your top RSS feeds, while on the move.

Where can I get one?

It's available in the UK only at present, and it's available to buy now. It's priced at £69.99 on Pay as You Go, and it's free with a contract from £15 per month.
