Hi guys,
I am not going to upgrade to 4.0x on my iPhone 3GS simply because my experience on another identical phone was that it just ground to a near stop.
However, on my 'non-modified unjailbroken phone', I do want to ask is there an app (or way) to image the iPhone in the present state, (with the 3.x )so that later on if 4.2 is installed but still bad, I can return it back to todays 3.01 state?
Informed best guesses welcome too...
Thanks
