writes "With YouTube's exclusive deals with mobile operators Verizon (in the US) and Vodafone (in the UK) coming to an end, the video sharing site has launched a mobile-friendly version that can be accessed by anyone with a compatible handset (capable of playing back .3gp video) and an appropriate data plan. With regards to the later, the first time you visit the site from your phone you're given the following warning: "YouTube Mobile is a data intensive application. We highly recommend that you upgrade to an unlimited data plan with your mobile service provider to avoid additional charges." What the site doesn't highlight is that many providers impose a 'fair use' policy which means that in reality they're unlimited plans aren't unlimited at all, as well as prohibiting access to non-partnering video sites as part of their terms of service. It will be interesting to see how the mobile industry responds to non-exclusive access to YouTube Mobile."
