iPhone OS 3.0 developer preview, sweeet!!!

Wow, right now Apple is holding a conference unveiling a developer preview to their iPhone OS 3.0, good things were announced today:

• Cut&Paste support
• Application push functionality, the ability to push notifications to your apps, things like "there's a new updated for your application, download a new version"
• In-app content distribution and purchase.
• Bluetooth goodness, now we will have more access to bluetooth functionality/programmability, we will be able to share files and stuff, really good
• Enhancements to spotlight.

Right now I'm waiting to get into http://developer.apple.com/iphone/ to see the new stuff but its content is still blocked, I assume that we will be able to see the new stuff there as soon as they have all the content up and running.
On the bad side, the update to 3.0 will only be free to iPhone 3G, but for ipod touch users there will be a small fee of $9.95
