iPhone OS 3.0

Now it's finally here - the iPhone OS 3.0.
After some glitches during update (in the middle of rebooting the screen flashed and it rebooted itself and iTunes popped up with a "iTunes could not connect to the iPhone, 0xE0000001" - pulled the USB cable and it finally upgraded fine - also registration with provider worked) I'm using the new OS successfully. What does that mean? It runs all the old apps that I already checked, the synch with Google addressbook and my 5 calendars works fine.
Tethering not yet but that seems to be Orange AT's issue.
It seems to be a bit "snappier" (as Apple called the UI behaviour on the WWDC eralier this year).
And a note to all the critics:
I'm not going crazy about all the "new" functions like Clipboard-operations, MMS (NEVER used that before on ANY mobile phone), landscape mode, tethering, etc. I'm just glad that these have finally arrived on the mobile device of my choice and let me lead my connected / online life a bit more comfortable than before. I am regarding my iPhone not as an integral part of my religious life but as a (very fine looking) mobile computer and "extension" to my home PCs which can also be used for calling or SMSing others. I don't know what I would want more from such a device. If I need more, I just use a computer. But I needn't carry one around - and that is what i like so much!
