Nokia's move into Internet operations faced headwinds on Friday, as the cellphone maker postponed the start of its gaming service due to software testing delays, and Warner pulled its songs from Nokia's music shop.

The gaming service and music shop are among the cornerstones of the world's top cellphone maker's big push into mobile Internet services under its new "Ovi" brand.

Nokia unveiled the long-awaited gaming service at a large media event in August, saying then it would be available globally in November.

"N-gage is coming in December. Software testing is taking a bit more time than what we had expected," Kari Tuutti said. "We are talking about a couple of weeks."

Nokia opened its first music store in Britain earlier this week, but Warner Music Group Corp is withholding its content from the site, partly over concerns about illegal downloads at Nokia's file-sharing site Mosh, the Wall Street Journal reported in its online edition.

Nokia is the first handset maker to move strongly into the content space with services like Mosh, where more than 6 million people have downloaded audio or video files, programs or documents.

Nokia plans to launch the music store next in Germany, France and Spain.
