Vodafone marked the end of a busy week on Friday with an agreement to launch YouTube on mobile phones.

The service will launch in the UK initially and will be expanded to key markets across Europe, allowing users to access a version of the popular YouTube service directly via Vodafone live!

As part of the service, YouTube will provide a daily selection of new videos. Subscribers can forward links for their favourite videos to friends and family, upload their own content from their mobile phones and search across multiple categories.

“People want to view and share favourite YouTube videos seamlessly wherever and whenever they want,” said Steve Chen, co-founder and chief technology officer for YouTube.

Earlier this week Vodafone announced a partnership with popular social networking site MySpace and online auction house eBay.
