New upgraded YouTube Mobile version available now
There are a couple of requirements for using the mobile version of the site: 1) you need a device that supports RTSP streaming and 2) your carrier has to allow streaming videos. Aside for the huge content that you can view, YouTube mobile now allows you to log into your account, where you can share videos, rate them and make comments. You can upload videos from your phone as well and they become available within moments.
The site now offers localized versions available for a few countries. In addition, there is a beta version of a YouTube downloadable Java application available in English only. The software supports the following phones: Sony Ericsson K800, W880; Nokia E65, N95, N73, 6110 Navigator and 6120 classic but their number will grow
