First impressions of iOS 4

The first thing you notice is that the upgrade process for iOS 4 (on my 16Gb iPhone 3G) can take a while. After about nine hours, and having interrupted installation of the apps in order to go to work, it is noticeable that I don't have any settings, contacts, music, videos, favourites, photos, texts or, possibly because of the interruption, working apps. What I do have is a working phone running iOS 4 that is currently syncing contacts from Exchange and which I can use, so not too bad.

Any improvements? Folders work really nicely although it is quite easy to drop apps in the wrong place creating strange groupings of apps (reorganising your phone on a moving train might have something to do with this). The combined email inbox is good and now sports "To" and "Cc" icons to indicate direct and copied email. The phone feels no slower and, occasionally, faster than it did running 3.1.3. Text replace work just as well as it does on the iPad.

The next step is to run a full sync and recover my missing media, but that will have to wait till this evening, after which more feedback.

Update: there are loads of application updates waiting to be downloaded as soon as a decent 3G signal pops up. They all list "iOS 4 compatibility" or something similar, the lack of which in my current apps probably explains their failure to launch.
