My son loves watching his favorite cartoon show on YouTube. He usually use my Nokia E63 cellular phone's YouTube application. His favorite videos include SpongeBob Squarepants, Phineas and Ferb and Ben 10.
He sometimes borrow my iPod Touch but watching a video on iPod's YouTube application drains the battery so fast, I have to charge 2 to 3 times a day. I wonder if there's an application that can download videos and the downloaded videos can be viewed even when offline?
