My guess is it wont be hard to get, BUT...with the old chip and battery, its gonna hog more memory on the 4, slowing it down and burning the battery...that would be my guess....

Just like how you can multitask on the iphone and 3g...but it slows it down
 
Yeah it would be good to try it though, you have to wonder if apple are only putting it on the 4S to make people upgrade or if it would work to an acceptable level, I love that jail breaking gives us the chance to find out! Get to work guys :)
 
Are you sure? I've seen it reported a lot that it is a GB of RAM...are those all just speculations? Wouldn't it have been announced at the conference?

They never announce RAM specs. It gets confirmed when ifixit does their teardown after the phone's released.
 
Looking forward to seeing how this works. I definitely think it' possible on the iPhone 4 since part of the lifting is done on Apple's server. If the jailbreak wizard get it working to a decent level, i'll definitely be strongly considering jailbreaking
