This morning a day after I upgraded to iOs 6 on my iPad 2 , I went to load some of Payasa Agapita videos on the iPad for my daughter I realized the YouTube app had disappeared.
According to other blogs apple no longer support a YouTube app with it core iOs structure. Google did respond by creating its own dedicated iOs app or the iPhone and an iPad-dedicated app is in plans.
In the meantime the colks at clickonline.com recommended using the Squrl and ShowYou in absence of an iPad Youtube App. I used Squrl and really liked that it brings videos from different platforms like Vimeo other than youtube.
