iPhone 4 - not right now because I am a bad person and do things like hack it. iOS 5 is fine for me, there won't be any landmark features outside no YouTube and Apple Maps. I think 6 will run well, I have not heard of any problems with the betas of iOS 6.
My iPad, on the other hand, I am waiting for my GM to download.
I plan on updating my iPhone 4S to iOS 6 but I am going to wait a couple of weeks and wait for the initial Oh-my-gosh-iOS-6-trashed-my-phone-and-killed-my-battery-life-erased-all-my-musi c-and-ruined-my-marriage posts to die down.
The maps app will still give directions on the iPhone 4 it simply wont give you audible turn by turn instructions voice by Siri. The directions will be text based like they are now. Apparently the processor in the iPhone 4 isn't powerful enough to run this feature.
iOS 6 looks really good, but it will have different levels of what it can do based on the hardware it is installed on. If I remember correctly all the bells and whistles will be available on the 5 and 4S, things like the turn by turn directions won't be available on the 4 and probably the other Siri functions that the newer phones are getting. The 3GS will load iOS 6 but my guess is that it will run kind of slow, the same way the 3G did when you loaded iOS 4.x on it or even tried to load up 5.x. The hardware just isn't sufficient to run the software. This is why Apple will stop supporting the 3GS now. Keeping up with 3 different hardware platforms is tough enough, I can't imagine trying to keep the current software running on old hardware.
in case anyone is confused and thinks this is a poll or a survey, that is not my intention at all: can anyone provide advice on downloading the new operating system onto an iphone 4 and any negative or positive effects of doing so on an iphone 4? also, i'm not understanding from apple's ios6 website if i can use the maps included in ios6 in the same way that i use the currently installed stock iphone 4 maps. does anyone know what turn by turn means in this case? the stock iphone 4 app provided turn by turn directions, they just aren't spoken. thanks for any help from anyone that has answers to the questions.

Other than to make sure your phone is backed up before you begin, not really. Anyone with firsthand experience is still under a NDA and can't talk about it.

If you look at http://www.apple.com/ios/ios6 you'll see that the turn by turn mapping is much more like a dedicated GPS unit than the old google maps app was.
