Two new features I've noticed with IOS 5

*You can move the tabs along or swap where the tab is on the iPad 2.

*Scripting updates so you can now type in a box like a forum or profile site where as before it would not let you type in the box. Worked in most sites just odd few but now works in all. Plus on forums you can scroll up like for a forum quote it was hard to get back to the top now you can smoothly scroll down. Or on the BBC news site you can scroll down a live feed alot smoother than before.

Discovering new things all the time.
