Well, I've taken the plunge and installed the iPhone OS 3.0 beta on my iPhone 3G.
... it's a one way trip just in case you didn't read bullet point 3 of the iPhone OS 3.0 beta pre-installation advisory notes.
I'm guessing this was a popular download as Apple's iPhone Dev Center site initially failed under the load.
Here's the cool stuff so far:
- Cut Copy Paste (it works well)
- Forwarding of text messages (which we had that around xmas)
- Landscape for mail, notes and the new messages app (SMS++)
- Global search (wish it had some filter icons eg apps only)
- Synchronisation of notes (but only to Apple Mail and Mobile Me)
Most painful experience was having to reorganise my 150+ icons :-(
