Iphone os 3.0 preview on march 17th

As many guys think this is not the launch of the firmware, just a preview.
The internet is abuzz with all sorts of requests.
Some of the most common ones are:

1. Copy and paste. Apple calls the iphone the most advanced phone but is still cannot do some basic tasks like copy & paste. If they don't release it this version, many people will be genuinely pissed off.
2. Video camera. Again this is another basic function. My 5 year old 6670 with a 1.3 mpx cam could do it without breaking a sweat. Well i guess "Most Advanced" has a different definition in cupertino! Even if they don't release it i wouldn't care because with 2 mpx the video is gonna be crappy.
3. MMS. Same story again. very basic stuff.
4. Bluetooth tethering. This i believe will be a definite component. I want to see AT&T's response. Will the jack the data plan even more? I can do this with my 15$ media net using my n95 8gb whereas iphone customers pay 30$ and still cant do it!
5. Bluetooth stereo. This has been with smarthphones since last 2 years. I guess it wont be in the next firmware also
6. Multi-tasking. This is by far the most important of them all. I am sure apple will not release this yet. If they do release it, i would like to see the performance of the apps after multiple apps are open. In fact this is one of the most important functions of a smart phone. What is the point of having thousands of apps if you cant use them simultaneously?

Well these are only some of the requested features. But i want to point out that all these are already in all of nokia's N series phones.

Should be interesting. Lets watch and see!
