Well, I upgraded within around 24 hours of iOS4’s being available on iTunes. The upgrade took quite a while, starting with a backup of the iPhone before uploading the new OS and finally restoring the iPhone.

I do like the new Mail functionality; the ordering of the Inboxes reduces the finger tap count quite considerably. I also like the folders, although that took a little while to get used to: the small icons can still be recognised if you forget which folder has which applications.

But the overall impression is of speed – lack of it! It takes ages to select something like a contact in Contacts. Email messages are not too slow to open, considering what you are doing with a small computer, but some applications grind almost to a halt. GPS MotionX is pretty horrendous, but that goes for any large application.

I might consider downgrading to iOS3 if I weren’t seriously considering replacing the iPhone with 4G ...

Note: I did downgrade that iPhone to iOS3.1.3 as my wife wanted to take over the device [added 15 Aguust 2010]. cb
