Visitors to Ringtones.com can now download tones from the Sony BMG UK back catalogue, encompassing both local and international artists.

The deal will also see Mobile Streams offer the content though its other channels, including mobilewallpapers.com, mobilebikinis.com and mobilecomedy.mobi.

It's been a busy month for Mobile Streams, which has also inked a licensing deal with pay TV giant HBO and launched ad-funded adult content.
