Mobile phone manufacturer Nokia is closing down the popular but controversial user-generated content service Mosh to focus more in its Ovi entertainment portal. Mosh was the sticking point behind Warner Music Group's decision to withhold it's catalog from the Ovi mobile music store.

The problem was that Mosh let users post anything they wanted, including content from various sources. Some of it was unauthorized content. Much of it was pornography. The result was some 137 million downloads.

Nokia said it plans to incorporate elements of Mosh and its sister service Download into the new Ovi store which is scheduled to go live in May. Unlike Mosh, all content made available will be screened prior to posting.
