yes, bro. iPod Touch would need to pay $9.95 for it while iPhone 2G users won't be able to utilise Stereo Bluetooth & MMS, even they're on 3.0.
@PeeEl
there's only peer to peer connectivity via bluetooth. IINM, no files transfer (except vCard). correct me if i'm wrong.

quoted from http://live.gizmodo.com/

"The new multiplayer connectivity allows you to bring up a dialog that lets you find local devices. The services provided are Automatic Discovery over Bluetooth (no Wi-Fi), no pairing, Bonjour, and isn’t just for games."

"But this isn’t just for games, it works for ANY P2P application. For example, apps that can send business cards to another phone, in a handshake-like manner."

Q: Could you qualify a bit more about the peer to peer. It looks like it’s available across the two iPhones, but it seems like you can do peer to peer with other Bluetooth devices.
A: It’s really a device to device Bluetooth connection. It’s 1 to 1, using Bluetooth and Bonjour to discover other devices and make an IP connection.

Q: So you can control devices…?
A: Yes, now you can, with third-party applications, control and talk to accessories over Bluetooth.
