I was able to get IOS 4.1 on my 2nd gen ipod touch early and my I say I am underwhelmed. While it seems a bit faster, on a 2nd gen touch, I do not get many of the cool features. No home screen wallpaper, no multitasking, no bluetooth keyboard!

If you are just going to IOS4 then you will be wowed. Having folders, grouping by a common theme,  for your apps is very nice. It makes finding the app you want much easier. For those of you with a 3rd gen device the wallpaper for you screen is nice. As an ipad user I like being able to change the view from my page when I wish, beach for the summer, mountains for a view, relaxing for those down times. I am anxiously waiting for IOS 4.2 for the iPad.

Get the latest version for your iPhone or touch as soon as is possible.  Let me know how the new version works you.
