Is the HTML5 source element bug fixed for iPad 2?

According to this page:

The first iPad has a bug that prevents it from reading more than one <source> element for HTML5 video. I would assume this is fixed in iPad 2, but can anyone confirm t开发者_如何学Gohis or provide a source link that confirms this?

According to Dive into HTML5, this bug is fixed in iOS 4.0.

iPad 2 initially shipped with iOS 4.3, so yup, this issue is fixed for iPad 2.

(And any iPad 1 users who experience the issue just need to plug their iPad into their internet-connected computer to upgrade their OS.)
