IOS4 update has reduced my poor little 3G model to the state of a Joey. I had a couple of days of whizz-bang fastness beforehand, and it was amazing, but now it's gone.
Usually, I'm quite conservative with updates and wait at least few weeks to read reviews, but overly-enthusiastic friends convinced me otherwise. How can I turn back time to the previous OS please? Waiting 5 seconds to read a text is not good for an impatient cow like me - have to think of blood pressure levels.

Stupid cocking iPhones.

Please, thank you :)
