Goodbye iPhone OS3, Hello iOS4!

So the day has finally arrived that my iPhone 3GS can look a little sexier for a few days before the iPhone 4 gets released.

The iOS4 update hit about 90 minutes ago, so obviously I was cool, calm and collected it and downloaded it immediately. :)

After a little initial bandwidth problem (it was stuck on "2 hours remaining" for about half an hour), I closed iTunes, restarted the download, and it took about 90 seconds.  Another five minutes to backup iPhone OS3, install and verify iOS4 and I'm now up and running.

Now for a pair of quick comparison screenshots : iPhone OS3 on the left, iOS4 on the right.

Obviously I don't have Apple's new Retina Display with the 3GS, but I am noticing that things seem to be displaying a little clearer than they did, perhaps due to new software to recalculate how resizing and font smoothing is done on the fly?

Not had much of a play so far, but the new "Folders" for organising the icons on your desktop into groups is looking rather nice. :)
